The maximum kinetic energy of the photoelectrons varies (a) inversely with the intensity of incident radiation and is independent of its frequency. (b) inversely with the frequency of incident radiation and is independent of its intensity. (c) linearly with the frequency of incident radiation and depends on its intensity (d) linearly with the frequency of incident radiation and is independent of its intensity.

Answer: (d). Einstein's equation: Kmax = hν - φ₀. This is a straight line in ν; intensity does not appear in it. So the answer is (d): varies linearly with frequency and is independent of intensity.

The maximum kinetic energy of the photoelectrons varies

Show answer and solution

Answer: (d)

Einstein's equation: $K_{max} = h\nu - \phi_0$ .
This is a straight line in $\nu$ ; intensity does not appear in it.
So the answer is (d): varies linearly with frequency and is independent of intensity.
