which of the following has the largest, velocity, frequency, wavelength, highest energy?

Question

Here are the choices.
Radio Waves
Light Waves
X-Rays
None of the above

My question is I need help find out which one has the largest Velocity, largest frequency, and largest wavelength , and then I need help find which one these have the highest energy? Can you please help me.

Answer 1

Velocity - Light

Frequency - X-Rays

Wavelength - Radio Waves

Highest Energy - X-Rays

Answer 2

Velocity -: They all travel at the speed of light in a vacuum (2.998 x 10^8 ms^-1)

i.e. Speed of Light = Frequency x Wavelength

Frequency -: X-Rays (Short Wavelength and High Frequency)

Wavelength-: Radio Waves (Long Wavelength and Low Frequency)

Highest Energy-: X-Rays (The higher the frequency the higher the Energy it carries)
From-: Energy = Planck Constant x Frequency

Answer 3

Radio waves, light waves and X-rays - all of them are electromagnetic radiation and have the same velocity in a given medium.

Radio waves have the largest wavelength out of the three choices.

X-rays have the largest frequency (shortest wavelength) and hence have the largest (highest energy). Energy of a photon is given by e = Planck's constant X frequency

So higher the frequency, the higher the energy.

Since frequency X wavelength = velocity which is constant in a given medium, we can calculate the frequency if we know the wavelength and vice versa. Velocity of light in vacuum is approx. 300,000 km per second. Velocity in air is almost same (slightly less) and in other media like water and glass, the velocity is given by velocity in vacuum/refractive index of the medium and since refractive index (mu in greek letters is commonly used) is always greater than 1, it means that the velocity of light in vacuum is the highest possible.

Answer 4

a million. distinctive colorations have not got a similar frequency. that's what a shade *is*: a undeniable frequency of radiation. distinctive colorations maximum actual have distinctive frequencies. 2. Monochromatic rays can not be divided right into a spectrum. in case you tried, you basically get the unmarried shade. simply by fact of this this is termed a "line spectrum," considering which you basically get one line of shade, no longer an entire rainbow. 3. something below microwaves is a radio wave. something greater than an X-ray is a gamma ray. 4. Frequency determines the ability of each and every individual photon. extra amplitude ability extra photons of this power. 5. it fairly is stated to be that way. 6. the electrical powered and magnetic fields work together in one in all those way that they obey the linear wave equation. 7. Partial mirrored image want no longer be from a skinny action picture.

Answer 5

I am answering your Questions based on the order of higher/highest energy.

X-rays have the highest energy from the list you have provided.

You will notice that gamma-rays have higher energy than X-rays.

Velocity is equal : Why

See the link below for Why and go section 2 on that for explanation.

Answer 6

they all have the same velocity

frequency and energy : radio waves the lowest, after light waves and X-rays the highest

Wavelength in order inverse of frequency

X-rays lowest, after light waves and radio waves : highest
