Q. Figure represents a graph of kinetic energy $K$ of photoelectrons and frequency $v$ for a metal used or cathode in photoelectric experiment. The work function of metal isPhysics Question Image

Dual Nature of Radiation and Matter

Solution:

$K_{\max }=h v-\phi_{0}$ (Einstein's photoelectric equation)
Above equation is equation of a straight line with $y$-intercept $\phi_{0}$, so from graph, work function is $1 \,eV$.
