According to Einstein's photoelectric equation, the graph of kinetic energy of the photoelectron emitted from the metal versus the frequency of the incident radiation gives a straight line graph line graph, whose slope

Options

A. depends on the nature of metal used
B. depends on the intensity or radiation
C. depends on both intensity of radiation and the nature of metal used
D. is the same for all metals and independent of the instensity or radiation

Answer

D

Explanation

`K_(max) = hf -W`
`K_(max) versus f graph is a straight line of slope h
(a universal constant).
