Which of the following occurs as the energy of a photon increases?
A) The frequency decreases.
B) The speed increases.
C) The wavelength increases.
D) The wavelength gets shorter.

Question

Quizplus · Accepted Answer

The energy of a photon is directly proportional to its frequency (E=hf). As the energy increases, so does the frequency, and since the speed of light is constant, the only way to increase frequency is for the wavelength to get shorter (inverse relationship between frequency and wavelength). Therefore, the correct answer is D - the wavelength gets shorter.
