Photoelectric effect is described as the ejection of electrons from the surface of a metal when:

In photoelectric emission, the velocity of electrons ejected from near the surface is

In photoelectric emission, the velocity of electrons ejected from near the surface is

In the photoelectric effect the velocity of the ejected electrons depends upon the nature of the target and

In the photoelectric effect the velocity of the ejected electrons depends upon the nature of the target and

In the photoelectric effect the velocity of the ejected electrons depends upon the nature of the target and

There are mainly three ways to eject an electron from the surface of metals. What are those?

If I_(0) is the threshold wavelength for photoelectric emission, 1 the wavelength of light falling on the surface of a metal and m is the mass of the electron, then the velocity of ejected electron is given by
