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. For a particular frequency of incident radiation, the maximum negative (retarding) potential given to the plate for which the photocurrent stops or becomes zero is called the cut-off or stopping potential. For a particular frequency of incident radiation, any negative (retarding) potential given to the plate for which the photocurrent stops or becomes zero is called the cut-off or stopping potential. none of the above |
