In This post you will get answer of Q.
A light beam consists of two types of photons. In one type each photon has energy $2eV$ and in other type each photon has energy $3eV$. The light beam is incident on a photoelectric material of work function $1eV$. The maximum kinetic energy of emitted photoelectron is
Solution:
Given.
work function of photoelectric material $(phi)=1 ,eV$
We know that
$K E_{max } =h v_{max }-phi$
$=3-1=2 ,eV$
