Which of the following statement is not true about stopping potential ( )?
- (A)It depends on the nature of emitter material.
- (B)It depends upon frequency of the incident light.
- (C)It increases with increase in intensity of the incident light.✓ Correct
- (D)It is times the maximum kinetic energy of electrons emitted.
Answer: (C)
Solution
Einstein's photoelectric equation: .
depends on the emitter's work function — option (1) is true.
increases with frequency — option (2) is true.
From , — option (4) is true.
depends only on frequency and work function, not on the intensity of light (intensity changes only the number of photoelectrons emitted, not their maximum kinetic energy). So the statement that "increases with increase in intensity" is the one that is NOT true.
