If threshold wavelength

\left( {{\lambda ^0}} \right)

for ejection of electron from metal is 330 nm. Then work function for the photo electric emission is

View answer and explanation

Correct option: C

6 \times {10^{ - 19}}J

Option C (

6 \times {10^{ - 19}}J

) is correct because it is the work function calculated using the threshold wavelength and Planck's constant.
