Question

What is effect of the intensity of incident radiation on the stopping potential in photoelectric emission

Answer 1

➡Stopping potential

Stopping potentialIf the frequency and the intensity of the incident radiation are fixed, the photoelectric current increases gradually with an increase in the positive potential on the collector electrode until all the photoelectrons emitted are collected.

Answer 2

There is no effect of the intensity of incident radiation on the stopping potential in photoelectric emission.

• The stopping potential in photoelectric emission from a metallic floor diminishes by cost-reducing the frequency of incident radiation if the frequency of incoming radiation is extra than the edge frequency.
• The preventing capacity is the terrible voltage implemented to the anode of a photoelectric tube at which the photoelectric contemporary quits or turns into zero.
• The preventing capacity is unaffected through the incident light's depth. As the depth rises, the costing of saturated contemporary rises, however, the preventing capacity remains constant. The preventing capacity is impartial of the incoming radiation's depth.
• Given the depth of radiation, the preventing capacity is frequency-dependent. The extra the preventing capacity, the better the frequency of incident rays.
