Questions

  1. 1.

    How does the energy of a single photon of electromagnetic radiation change if its wavelength is halved?

    • A) It is halved because photon energy is directly proportional to wavelength.
    • B) It remains unchanged because photon energy depends only on wave speed.
    • C) It doubles because photon energy is inversely proportional to wavelength.
    • D) It quadruples because photon energy depends on the square of the frequency.
