The stopping potential necessary to reduce the phtoelectric current of zero-

A

Is directly proportional to wavelength of the incident radiation

B

Increases uniformly with wavelength of the incident radiation

C

Is directly proportional to frequency of the incident radiation

D

Decreases uniformly with the frequency of the incident radiation

Text Solution

Verified by Experts

The correct Answer is:
C
`K_("max") = hf -phi_0`
`implieseV_0 =hf -phi_0implies V_0 =(h/e)f -phi_0/e`
`implies V_0 prop f`

The stopping potential eV_s depends on

Radiation of wavelength 546 nm falls on a photo cathode and electrons with maximum kinetic energy of 0.18 eV are emitted. When radiation of wavelength 185 nm falls on the same surface, a (negative) stopping potential of 4.6 V has to be applied to the collector cathode to reduce the photoelectric current to zero. Then, the ratio (h)/(e) is
