, electrons are emitted from the surface. The most energetic electron coming out of the surface have kinetic energy equal to the

Consider a small metallic plate of chromium, having only 5 free electrons on the surface. We shine light on the plate and we observe that these electrons come out but with different energies.

The energy received by each electron is 10 eV. Below is the list of energies with which each electron comes out.

e1 = 2.5 eV.

e2 = 2.7 eV.

e3 = 4.5 eV.

e4 = 5.5 eV.

e5 = 4.7 eV.

If one of these electrons has most optimally used the energy provided to come out, then what could be the work function of the metal chromium?

Q. It has been found that, when the surface of metal is irradiated with radiation of suitable frequency, electrons (photo electrons) are ejected from the surface of metal. Minimum energy required for ejection of electron from metal surface is called work function of metal.

A metallic surface is irradiated alternatively with radiations of wavelength 3000

A^{\circ}

and 6000

A^{\circ}

. It is observed that the maximum speeds of the photoelectrons under these cases are in the ratio 3:1.
