According to Einstein's photoelectric equjation , the plot of the kinetic energy of the incident radaiation given as straight the whose used slope

A

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

B

depend on the intensity of the radiation

C

depends on the nature of the metal used

D

is the for the all metal s and independent of the intensity of the radiation

Text Solution

Verified by Experts

The correct Answer is:
D

From Equation `K.E = hv - phi`
slope of graph of `K.E and v is h `(plank's constant) which is same for all metals
