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. 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

Answer

D

Explanation

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.
