If you double the wavelength, the electromagnetic radiation energy will double. The energy of the electromagnetic radiation will halve if you halve the wavenumber. When the frequency of the light is doubled, its energy will .

It's energy will double.

Explanation:

This is because energy, E, is related to frequency, f, by:

E = hf

Where h = Planck's constant

So, double frequency will be 2f

=> E(2f) = 2hf = 2E.

Hence, energy is doubled.
