Which statement about gamma rays is true?

Explanation:
The amount of energy a photon carries depends on its frequency: higher frequency means higher energy (E = h f). Gamma rays have the highest frequency in the electromagnetic spectrum, so their photons carry the most energy. They also travel at the speed of light in vacuum, just like all other electromagnetic waves, so they are not slower than light. And they are not visible to the human eye, which only sees visible light. Because of those points, the statement that gamma rays have the highest frequency and energy is true.
