Question

7 types of electromagnetic waves
which electromagnetic waves have the highest frequency / highest energy?
a microwaves
b radio waves
c x - rays

Explanation:

In the electromagnetic spectrum, gamma - rays have the shortest wavelength and highest frequency. According to the formula $E = h
u$ (where $E$ is energy, $h$ is Planck's constant, and $
u$ is frequency), higher frequency means higher energy.

Answer:

D. Gamma - rays
