All the photoelectrons are not emitted with same energy. Give reason.

Text Solution

Verified by Experts

The energy of the incident photons is spent for providing work function and KE. Work function is the same for all electrons then `KE_("max")` changes depending on its energy state.

B. Write Einstein's Photo-Electric Equation and explain the terms in it. C. All photo electrons are not emitted with the same energy as the incident photons. Why?

Answer the following questions: (d) Every metal has a definite work function. Why do all photoelectrons not come out with the same energy if incident radiation is monochromatic? Why is there an energy distribution of photoelectrons?

a. Every metal has a definite work function. Why all photoelectrons do not come out with the same energy of incident radiation in monochromatie ? Why there is an energy distribution of photoelectrons? b. The energy and momentum of an electron are related to the frequency and wave-length of the associated matter wave by the relations, E=h upsilon, p=(h)/(lambda) But while the value of lambda is physically significant, the value of upsilon (and therefore the value of the phase speed upsilon lambda has no physical significance. Why?

HIV is a retrovirus. Give reason.

In an experiment on photoelectric effect, a photon is incident on an electron from one direction and the photoelectron is emitted almost in the opposite direction. Does this violate conservation of momentum ?

If m_(e ) is the mass of the photoelectron emitted with a velocity of 2 m//s then the kinetic energy associated with it is "____________" units.
