In photoelectric effect, stopping potential depends on

A

frequency of the incident light

B

intensity of the incident light by varies surce distance

C

emitter's properties

D

frequency and intensity of the incident light

Text Solution

Verified by Experts

The correct Answer is:
A, C
`hv = hv_(0) + eV_(s) , V_(s) = ((hv - hv_(0)))/(e) , eV_(s) = hv - phi`
Here `v=` frequency of incident light and `phi =` properties of emitter

    What is photoelectric effect?

    A student performs an experiment on photoelectric effect,using two materials A and B.A plot V_("stop")vs v is given in figure. (i)Which material A or B has a higher work function? (ii)Given the electric charge of an electron =1.6xx10^(-19) C,find the value of the h obtained from the experiment for both A and B.Comment on whether it is consistent with Einstein's theory:

    Explain : Photoelectric effect.

    Statement-1 : In photoelectric effect, the number of photoelectrons emitted is always equal to number of photons incident. and Statement-2 : All the photons fallin on the surface will eject photoelctron, is not necessary.

    Work function of metal in photoelectric effect is 3.5 eV for -1.2 V potential photoelectric current become zero,Hence…….
