According to Einstein's photoelectric equation graph of kinetic energy of emitted photo electrons from metal versus frequency of incident radiation is linear .Its slope……

A

depends on the nature of the metal used

B

depends on the intensity of the radiation

C

depends both on the intensity of the radiation and the metal used

D

is the same for all metals and independent of the intensity of the radiation

Text Solution

Verified by Experts

The correct Answer is:
D
According to Einstein's equation of photoelectric effect `hf=W_(0)+K_("max"), K_("max")=(h)f-W_(0)`

The slope of K vs f graph is h which is a fundamental constant and same for all metals at all intensifies.

In an experiment on photoelectric effect, the slope of the cut-off voltage versus frequency of incident light is found to be 4.12xx 10^(-15) v s . Calculate the value of Planck’s constant.

Statement-1 : In a photoelectric effect experiment different photoelectron have different kinetic energy. and Statement-2 : In the incident radiation different photons must have different energy.

Assertion : Though light of a single frequency (monochromatic) is incident on a metal , the energies of emitted photoelectrons are different. Reason : The energy of electrons emitted from inside the metal surface is lost in collision with the other atoms in the metal.
