Question

1. which of the following electromagnetic waves has photons of the highest energy? radio waves gamma rays ultraviolet x rays

Explanation:

The energy of a photon is given by the formula $E = h
u$, where $h$ is Planck's constant and $
u$ is the frequency. In the electromagnetic - spectrum, gamma rays have the highest frequency. Higher frequency means higher energy photons.

Answer:

B. gamma rays
