What is stopping potential? |
For a particular frequency of incident radiation, the minimum negative (retarding) potential given to the plate for which the photocurrent stops or becomes zero is called the cut-off or stopping potential. Photocurrent does not depends upon Intensity of light. Photocurrent depends upon frequency of incident light. none of the above |
