A plot of kinetic energy of emitted photoelectrons from a metal versus the frequency of incident radiation gives a straight line, the intercept of which
A. Depends on the nature of the metal used
B. Depends on the intensity of radiation
C. Depends both on the intensity and the nature of metal used
D. Is a constant and is same for all metals which is independent of the intensity of Incident radiation
- A A
- B B
- C C
- D D
Answer & Solution
Correct Answer
(A) A
Step-by-step Solution
Detailed explanation
According to Einstein's photoelectric equation, the kinetic energy \(K_{max}\) of emitted photoelectrons is given by \(K_{max} = h\nu - \Phi\), where \(h\) is Planck's constant, \(\nu\) is the frequency of incident radiation, and \(\Phi\) is the work function of the metal.…
