Q. The correct graph respectively the relation between energy $(E)$ of photoelectrons and frequency $v$ of incident light is

AIIMSAIIMS 2014

Solution:

If using light of different frequencies a graph is plotted between the maximum kinetic energy $E_{k}$ of the photoelectron and frequency $v$ of light, then a straight line is obtained, according to relation $E_{k}=h v_{0}-w$, where $w$ is the intercept cut by straight line on negative $E_{k}$-axis.
