Question

If Energy is quantized,then how can a photon transfer some energy when it collides with an electron? Someone kindly clear my doubt​

Answer 1

Answer:

When a photon is emitted or absorbed, it transfers ħ of angular momentum and the associated energy is also transferred. ... The energy transfer between the photon and the electron does not involve the transfer of quantized angular momentum, therefore only part of the photon's energy can be transferred
