Which of the following statement is wrong regarding the photo electric effect.
- A The maximum kinetic energy of the electrons emitted depends on the intensity of the incident radiation
- B Photo electric current is directly proportional to the intensity of the incident radiation
- C The maximum kinetic energy of the electrons emitted depends on the frequency of the incident radiation
- D The value of the stopping potential increases with the increase in frequency of the incident radiation.
Answer & Solution
Correct Answer
(A) The maximum kinetic energy of the electrons emitted depends on the intensity of the incident radiation
Step-by-step Solution
Detailed explanation
According to Einstein's photoelectric equation, the maximum kinetic energy 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. From this…
