Show that it is not possible for a photon to be completely absorbedby a free electron.

It is not possible for a photon to be completely absorbed by a free electron. Explain.

It is not possible for a photon to be completely absorbed by a free electron. Explain.

In a phtoelectron effect energy of photon is directly proportional to the frequency and photons are totally absorbed by the electrons of metals then frequency and photons are totally absorbed by the electrons of metals then photoelectric current is:

What is the speed of photon in free space?

Statement-1: In Photoelectric effect , electrons absorbing the photon can not be a free electron. Statement -2: A free electron can't absorb a photon completely

Statement-1: In Photoelectric effect , electrons absorbing the photon can not be a free electron. Statement -2: A free electron can't absorb a photon completely

free fall is possible only in air .

(i) Show that a free electron at rest cannot absorb a photon and thereby acquire kinetic energy equal to the energy of the photon. Would the conclusion change if the free electron was moving with a constant velocity ? (ii) If the absorption of a photon by a free electron is ruled out as proved in (i) above, how does photoelectric emission take place at all ?

The de-Broglie wavelength of a photon is the same as the wavelength of electron, show that kinetic energy of photon is (2mclambda)/h times the kinetic energy of electron, where m is the mass of electron and c is the velocity of light.
