According to Einstein's photoelectric equation, the graph between kinetic energy of photoelectrons ejected and the frequency of incident radiation is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
According to Einstein's photoelectric equation,
Compare it with equation of straight line, . Graph will be a straight line with slope '
'
As the electrons are ejected when the light of frequency more than threshold frequency falls on the metal surface, thus till , no photoelectrons are emitted.
