Question: When the photons of energy ![](https://cdn.pureessence.tech/canvas_22.png?top_left_x=1584&top_left_y...

When the photons of energy fall on a photosensitive metallic surface of work function hv0h v _ { 0 } electrons are emitted from the surface. The most energetic electron coming out of the surface have kinetic energy equal to:

A

B

C

D

hv−hv0h v - h v _ { 0 }

Answer

hv−hv0h v - h v _ { 0 }

Explanation

Solution

: Maximum kinetic energy of emitted photoelectrons

=hv−hv0= h v - h v _ { 0 }
