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

Options

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

Answer

A

Explanation

`hv = hv_(0) + KE_(max) rArr KE_(max) = hv - hv_(0)`
On comparing this equation with `y = mx + c` , we get `m = h =` Universal constant
