The relationship between energy of a photon of light and its frequency is given by________________?
Correct answer: C. Plancks Quantum theory
- A. de-Broglie duel nature of matter
- B. Bohrs model
- C. Plancks Quantum theory
- D. Rutherfords atomic model
Explanation
Planck's quantum theory gives the photon-energy relation E = hν, where h is Planck's constant and ν is frequency. Thus, photon energy is directly proportional to frequency. Students may choose b because Bohr also used quantized energy levels, but the direct energy-frequency relationship was introduced by Planck's theory.

About Planck's Quantum Theory
Planck's quantum theory states that energy is emitted or absorbed in discrete packets called quanta, with each packet having energy E = hν. It covers the meaning of Planck's constant, the relationship between frequency and wavelength, and how quantisation differs from the classical continuous model of energy.
