What is the relationship between the energy of a photon and the frequency of incident radiation according to Planck’s quantum theory?
What is the relationship between the energy of a photon and the frequency of incident radiation according to Planck’s quantum theory?
- E is inversely proportional to the frequency, E ∝ 1/ν
- E is directly proportional to the frequency, E ∝ ν (correct)
- E is inversely proportional to the wavelength, E ∝ 1/λ
- E is directly proportional to the wavelength, E ∝ λ
