The following graph shows the variation of stopping potential with frequency of the incident radiation for two photosensitive metals and :
Which metal,
(i) has smaller threshold wavelength.
(ii) has smaller kinetic energy.

What is photo-electric effect?

For a certain metal threshold wavelength is . Calculate the work function of the metal.

When a metallic surface is illuminated with light of frequency the maximum kinetic energy of emitted electrons is . When the same surface is illuminated by light of frequency the maximum kinetic energy of emitted electrons is . Find out work function of the metal.
