The amount of energy associated with quantum of radiation is directly proportional to:

Correct answer: C. Frequency

  • A. Photon
  • B. Wavelength
  • C. Frequency
  • D. Velocity

Explanation

According to E = hf, it can be seen that 'E' (energy of quantum) is directly proportional to 'f' (frequency). Velocity, photon, and wavelength have no effect on the energy of quantum.

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.
