When an `X`-ray photon collides with an electrons and bounces off, its new frequency

(i) In the explanations of photoelectric effect, we assume one photon of frequency v collides with an electron and transfer its energy. This leads to the equation for the maximum energy E_(max) of the emitted electron as E_(max)=hv-phi_(0) Where phi_(0) is the work function of the metal. if an electron absorbs 2 photons (each of frequency v) what will be the maximum energy for the emitted electron? (ii) Why is this fact (two photon absorption) not taken into consideration in our discussion of the stopping potential?

(i) In the explanations of photoelectric effect, we assume one photon of frequency nu collides with an electron and transfer its energy. This leads to the equation for the maximum energy E_(max) of the emitted electron as E_(max)=hnu-phi_(0) Where phi_(0) is the work function of the metal. if an electron absorbs 2 photons (each of frequency v) what will be the maximum energy for the emitted electron? (ii) Why is this fact (two photon absorption) not taken into consideration in our discussion of the stopping potential?

An X-ray tube is operated at 30 eV. If a particular electron loses 10% of its kinetic energy to emit an X-ray photon during the collision. Find the wavelength and maximum frequency assoicated with this photon.

The wavelength of a photon is 1.4 Å . It collides with an electron. Its wavelength after collision is 2.0 Å . Calculate the energy of the scattered electron.

When a stream of electrons collides with a stream of photons in this collision which of the following is not conserved ?

A positron of 1MeV collides with an electron of 1MeV and gets annihilated and the reaction produces two gamma- ray photons. If the effective mass of each photons is 0.0016amu, then the energy of each gamma- ray photon is about-
