Question
When photons of energy hv fall on a photo sensitive metallic surface (work function hv0) electrons are emitted from the metallic surface. This is known as photoelectric effect. The electrons coming out of the surface have a K.E. It is possible to say that-
Options
A.All ejected electrons have the same K.E. equal to hv - hv0.
B.The ejected electrons have a distribution of K.E., the most energetic ones having K.E. equal to hv - hv0.
C.The most energetic ejected electrons have K.E. equal to hv.
D.The K.E. of the ejected electrons is hv0.
