Photons from a source each have energy 3.30 eV.Photons from a second source have double the frequency of those from the first source.What is the energy of a photon from the second source?
A) 6.60 eV
B) 13.2 eV
C) 1.65 eV
D) 0.825 eV
E) 3.96 eV

Question

Quizplus · Accepted Answer

The energy of a photon is directly proportional to its frequency. If the frequency is doubled, the energy is also doubled. Therefore, the energy of a photon from the second source is 2 * 3.30 eV = 6.60 eV.

Photons from a Source Each Have Energy 3
