Suppose you know the frequency of a photon and the speed of light. What else can you determine about the photon?
A) Its wavelength and energy
B) Its temperature
C) Its acceleration
D) The chemical composition of the object that emitted it

Question

Quizplus · Accepted Answer

The frequency of a photon is directly proportional to its energy and inversely proportional to its wavelength. Therefore, knowing the frequency and the speed of light (which is a constant), we can calculate the wavelength and the energy of the photon using the equations E = hf (where h is Planck's constant) and c = fλ (where c is the speed of light).
