Question

A light beam consists of two types of photons. In one type, each photon has the energy $2 eV$ and in another type, each photon has energy $3 eV$ . The light beam is incident on a photoelectric material of work function $1 eV$ . The maximum kinetic energy of emitted photoelectron is

Options:

Answer:

A

Solution:

Given,

Work function of photoelectric material $(ϕ) = 1 e V$

We know that,

$K E_{m a x} = h v - ϕ$

$= 3 - 1 = 2 e V$
