Question

assuming two light waves have the same amplitude, which one would carry the most energy?
a low - frequency red light wave.
a light wave with a very low amplitude.
a high - frequency violet light wave.
a light wave traveling through a vacuum.

Explanation:

The energy of a light wave is related to its frequency by the formula $E = hf$, where $h$ is Planck's constant and $f$ is frequency. Higher frequency means higher energy. The problem states both waves have the same amplitude, so amplitude is not a factor here. The speed of light in a vacuum does not affect its energy content. Violet light has a higher frequency than red light, so it carries more energy.

Answer:

C. A high-frequency violet light wave.
