Does energy of photo electrons depend on light

Question

See the modern theory of einstein

Answer 1

Yes, the energy of photoelectrons depends on the frequency of light. Higher frequency light gives more energy to photoelectrons, as described by the equation:

Energy = h × f - φ or

Where:

1. h is Planck's constant,
2. f is the frequency of light,
3. φ is the work function of the material.

The intensity of light only affects the number of photoelectrons, not their energy.
