Question

stopping potential of blue filter

Answer 1

The kinetic energy of the photoelectron depends only on the frequency of the incident light. If the frequency of light increases, the energy will increase. Obtain the stop potentials for different colour leds. Draw a graphic of Stop Potential vs Frequency.

Answer 2

-----hey mate here is your ans----

The stopping potential is defined as the potential necessary to stop any electron (or, in other words, to stop even the electron with the most kinetic energy) from 'reaching the other side '. As you already stated, the maximum kinetic energy is given by.
