## The longest wavelength within the visible spectrum is light

The longest wavelength within the visible spectrum is light

## Arrange the following in order from the shortest wavelength to the longest wavelength.

So I am assuming that by “the following,” you mean in general terms.

The shortest wavelength of the spectrum is the Gamma Ray waves, they are 400nm and are the most deadly, because of how often and frequent they are able to vibrate. Shorter the wavelength the more active.

So the list from “shortest,” to “longest,” is,

Gamma Ray, X-Ray, Ultraviolet, Visible, Infrared, Microwave, and Radio wavelengths.

In the spectrum, Radio has the longest and furthest traveling waves. This means that they are not harmful and that they can travel extreme distances.

Hope this helps!

## Relative to ultraviolet waves, the wavelength of infrared waves is

The double-slit experiment is a famous tool to illustrate concepts within quantum mechanics. In particular it demonstrates the concept of wave-particle duality. Use of a light wave demonstrates diffraction and interference, which is a typical wave behaviour. Surprisingly, use of a beam of electrons also yields an interference pattern, showing electrons can behave like waves.

Explanation:

There would be a optical phenomenon pattern almost like, however totally different from, that exploitation light-weight.Interference and optical phenomenon are the phenomena that distinguish waves from particles: waves interfere and split, particles don’t.

Light bends around obstacles like waves do, and it’s this bending that causes the one slit optical phenomenon pattern.

## Blue light, which has a wavelength of about 475 nm, is made to pass through a slit of a diffraction grating that has 425 lines per mm and forms a first-order bright band. What is the angle of diffraction? Round answer to the nearest whole number.

a) The time the police officer required to reach the motorist was 15 s.

b) The speed of the officer at the moment she overtakes the motorist is 30 m/s

c) The total distance traveled by the officer was 225 m.

Explanation:

The equations for the position and velocity of an object moving in a straight line are as follows:

x = x0 + v0 · t + 1/2 · a · t²

v = v0 + a · t

Where:

x = position at time t

x0 = initial position

v0 = initial velocity

t = time

a = acceleration

v = velocity at time t

a)When the officer reaches the motorist, the position of the motorist is the same as the position of the officer:

x motorist = x officer

Using the equation for the position:

x motirist = x0 + v · t (since a = 0).

x officer = x0 + v0 · t + 1/2 · a · t²

Let´s place our frame of reference at the point where the officer starts following the motorist so that x0 = 0 for both:

x motorist = x officer

x0 + v · t = x0 + v0 · t + 1/2 · a · t²      (the officer starts form rest, then, v0 = 0)

v · t = 1/2 · a · t²

Solving for t:

2 v/a = t

t = 2 · 15.0 m/s/ 2.00 m/s² = 15 s

The time the police officer required to reach the motorist was 15 s.

b) Now, we can calculate the speed of the officer using the time calculated in a) and the  equation for velocity:

v = v0 + a · t

v = 0 m/s + 2.00 m/s² · 15 s

v = 30 m/s

The speed of the officer at the moment she overtakes the motorist is 30 m/s

c) Using the equation for the position, we can find the traveled distance in 15 s:

x = x0 + v0 · t + 1/2 · a · t²

x = 1/2 · 2.00 m/s² · (15s)² = 225 m

## What does the term wavelength refer to?

The frequency of light that has a wavelength of 249 nm is about 1.20 × 10¹⁵ sec⁻¹

### Further explanation

The term of package of electromagnetic wave radiation energy was first introduced by Max Planck. He termed it with photons with the magnitude is :

E = Energi of A Photon ( Joule )

h = Planck’s Constant ( 6.63 × 10⁻³⁴ Js )

f = Frequency of Eletromagnetic Wave ( Hz )

The photoelectric effect is an effect in which electrons are released from the metal surface when illuminated by electromagnetic waves with large enough of radiation energy.

E = Energi of A Photon ( Joule )

m = Mass of an Electron ( kg )

v = Electron Release Speed ( m/s )

Ф = Work Function of Metal ( Joule )

q = Charge of an Electron ( Coulomb )

V = Stopping Potential ( Volt )

Let us now tackle the problem !

Given:

λ = 249 nm = 2,49 × 10⁻⁷ m

## A certain string on a piano is tuned to produce middle c (f = 261.63 hz) by carefully adjusting the tension in the string. for a fixed wavelength, what is the frequency when this tension is tripled?

1) Water has very high specific heat.

2) It expands when it freezes

3) ability to dissolve in ionic substances

4) Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid.

Explanation:

1) Water molecules due to their high specific heat , undergo relatively less increase in temperature after absorbing heat. So they prevent their adjoining area to experience sharp increase in temperature.

2) Water is an example which expands on freezing. In it , large spaces are left between molecules when it cools. It happens because hydrogen bonds prevent any two molecules to come very close thereby  creating gaps. This gap is filled up when ice melts , which results in overall reduction in volume of water.

3) Uneven distribution of charge results in water molecules becoming polar in nature . A polar substance  can be dissolved in polar solvents only.

4) It is due to property of surface tension. Property  of surface tension results due to molecules of water near the surface experiencing a  net downward  force due to hydrogen bonds . It is due to fewer hydrogen bonds made by them.

## Which diagram represents electromagnetic energy with the shortest wavelength?

The force diagram has four forces: two in the horizontal direction (west – east) and two in the vertical direction (up and down).

The two forces in the horizontal direction are:

1) Force of friction, Ff = 360 N east.

2)  Force applied = 1330 N west

=> Net horizontal force = 1330N west – 360N east = 970 west.

Vertical forces:

3) Weight = 990 kg * 9.8 m/s^2 = 9,702 N downward

4) Normal force = – weight = – 9,702N upward

Net vertical force = 9,702N downward – 9,702N upward = 0

5) Second Law of Newton

Net force = m * a => a = Net force / m = 970 N west / 990 kg = 0.98 m/s^2

Then, the conclusion is that the car is moving with uniform acceleration of 0.98 m/s^2 westward (that magnitud is 10% of gravitational acceleration)

## If you send a sound wave of the same wavelength (λ = 2.00 m) through air, helium, and carbon dioxide, describe how the pitch of the sound will compare through each medium.

Electrical pressure, called “electro-motive force” (EMF), is what causes current
to flow in an electrical circuit. EMF is measured in volts. Pressure and the quantity of electricity transmitted can be considered analogous to pressure and quantity of water flowing in pipes: the longer the distance, the higher is the flow of water (called the “flow of electrical charge, which is also known as the “electric current”). That is why, for long distance transmission, high pressure (voltage for electricity) is required, failing which, the current – and therefore the power – will not reach the intended destination. Instead, it will be lost (also called “dissipate”) along the way. We can think of electrical

current as the quantity of electricity which will be drawn from the pipeline

cables for electricity) at the pressure (= voltage) required.

## Visible light with a wavelength of 480 nm appears as what color?

Answer: The correct option is B.

Explanation:

Transverse wave is a wave in which the vibration of the particles travels in the perpendicular direction to the propagation of wave. It does not require any medium to travel. It consists of crest and troughs. For example light wave. It travels faster at higher temperature.

Longitudinal wave is a wave in which the vibration of the particles travels in the parallel direction to the propagation of wave. It requires a medium to travel. It consists of compression and rarefaction. For example sound wave. It travels faster at higher temperature.

Therefore, the common characteristic between transverse wave and longitudinal is both move faster at higher temperature.

2.The difference between continental drift and plate tectonics is that the theory of continental drift states that the world was made up of a single continent.The theory of plate-tectonics, on the other hand, states that earth’s surface is broken into numbers of shifting plates or slabs.

3.The tectonic plates are made up of Earth’s crust and the upper part of the mantle layer underneath. Together the crust and upper mantle are called the lithosphere and they extend about 80 km deep.May 21, 2008

4.The continental crust is the layer of granitic, sedimentary and metamorphic rocks which form the continents and the areas of shallow seabed close to their shores, known as continental shelves. It is less dense than the material of the Earth’s mantle and thus “floats” on top of it.

6.Trenches are formed by subduction, a geophysical process in which two or more of Earth’s tectonic plates converge and the older, denser plate is pushed beneath the lighter plate and deep into the mantle, causing the seafloor and outermost crust (the lithosphere) to bend and form a steep, V-shaped depression.
