How are wavelength,frequency,and energy related for photons of light?
A)Longer wavelength means lower frequency and lower energy.
B)Longer wavelength means higher frequency and lower energy.
C)Longer wavelength means higher frequency and higher energy.
D)Longer wavelength means lower frequency and higher energy.
E)There is no simple relationship because different photons travel at different speeds.

Question

Quizplus · Accepted Answer

The relationship between wavelength, frequency, and energy for photons of light is described by the equation E = hf, where E is the energy of the photon, h is Planck's constant, and f is the frequency of the photon. This equation shows that as the frequency of the photon increases, the energy of the photon increases, but as the wavelength of the photon increases, the frequency and energy decrease. Therefore, choice A is the correct answer.
