Electrons ejected from the surface of a metal, when light of cartain frequency is incident on it, are stopped fully by a retarding potential of 3 volts. Photo electric effect in this metallic surface begins at a frequency 6 x 1014 s-1 . The frequency of the incident light in s-1 is [ Planck′s constant = 6.4 x 10-34 J − sec ; charge on the electron = 1.6 x 10-19C ]

Solution:

According to Einstein's Photo electric equation
hv = hv0 + K.E = hv0 + ev0
⇒ v0 = v0 + ev0 /h
⇒' v0 = 13.5 x1014 Js-1
