The time required in emitting photoelectrons is

The kinetic energy of emitted photoelectrons is independent of …………………

At stopping potential, the kinetic energy of emitted photoelectron is

When light of wavelength 3000 Å falls on a photosensitive surface (A) photoelectrons are emitted. However, for another photoemitter (B), light of wavelength 6000 Å is required for the emission of photoelectrons. What is the ratio of the work functions of A and B ?

What will be the kinetic energy of emitted photoelectrons if light of threshold frequency falls on a metal?

In the previous problem , which surface will require less energy to emit photoelectrons ?

0.24eV of energy is required to stop photoelectron emitted by radiation of wavelength 2480 Å . Find work function of metal used?
