Questions and Answers

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

    • What happens to the frequency of a photon when it goes from one medium to another?

  • Its frequency decreases
  • Its frequency does not change (correct)
  • Its frequency becomes zero
  • Its frequency increases

    • What happens to the speed of a photon when it moves from one medium to another?

  • The speed of light at empty space (correct)
  • The speed increases
  • The speed becomes zero
  • The speed decreases
