Question

Which light has highest frequency?

Answer 1

Answer:

gamma rays

Explanation:

Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.

Answer 2

Explanation:

Violet.

Explanation:

Violet waves have the most energy of the visible spectrum.

Remember: c=fλ

Therefore: f=

λ

c

Here c is the speed of light in a vacuum.

So:

As wavelength decreases, frequency increases and, as E=hf, where h is constant (Planck's constant), so does the energy that the waves carry. Waves with a short wavelength have the most energy.

Red waves have a relatively long wavelength (in the 700nm range), and violet waves are much shorter - roughly half that.

Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy.
