Question

which of the following has the highest energy?
red light
gamma
uv
microwave

Explanation:

In the electromagnetic spectrum, energy is related to frequency (and inversely to wavelength) by the formula \( E = hf \) (where \( h \) is Planck's constant and \( f \) is frequency). Gamma rays have the highest frequency among red light (visible), UV (ultraviolet), microwave, and gamma rays. Higher frequency means higher energy. So gamma rays have the highest energy.

Answer:

B. Gamma
