Question

Which one of the following is not the characteristic of Planck's quantum theory of radiation?

• A. The energy is not absorbed or emitted in whole number multiple of quantum
• B. Radiation is associated with energy
• C. Radiation energy is not emitted or absorbed continuously but in the form of small packets called quanta
• D. This magnitude of energy associated with a quantum is proportional to the frequency

Answer 1

Answer: (A)

The energy is not absorbed or emitted in whole number multiple of quantum

Radiation energy is not emitted or absorbed continuously but in the form of small packets called quanta. This magnitude of energy associated with a quantum is proportional to the frequency and inversely proportional to wavelength.
$E=h\nu =\frac{hc}{\lambda }$

The option (A) is not the characteristic of Planck's quantum theory of radiation.
