The threshold frequency of the metal of the cathode in a photoelectric cell is 1×10^15Hz. When a certain beam of light is incident on the cathode, it is found that a stopping potential 4.144 V is required to reduce the current to zero. The frequency of the incident radiation is it is found that a [...]
