Which of the following is not a characteristic of Planck's quantum theory of radiation?
Which of the following is not a characteristic of Planck's quantum theory of radiation?
The correct option is A Energy is not absorbed or emitted in whole number multiples of quantum.
When Planck explained his theory. He took some assumptions. They are:
a.Each radiation is always associated with a definite amount of energy and is known as radiant energy.
b.Radiant energy is emitted or absorbed discontinuously in the form of small packets of energy called quanta. Each wave packet or quantum is associated with a definite amount of energy. In case of light, the quantum of energy is called photon.
c.The amount of energy associated with a quantum of radiation is proportional to the frequency of radiation.
E α ν or E = hν = hcλ
d.The energy emitted or absorbed by a body is always an integral multiple of quanta, i.e., E = nhν, where n = 1, 2, 3, ... etc.
⇒ Energy emitted or absorbed by a body is always an integral not whole number multiples of quantum.
