The light emitted in the transition n = 3 to n = 2 in hydrogen is called H_α light. Find the maximum work function a metal can have so that H_α light can emit photoelectrons from it.

Question

The light emitted in the transition n = 3 to n = 2 in hydrogen is called H α light. Find the maximum work function a metal can have so that H α light can emit photoelectrons from it.

Philoid · Accepted Answer

Maximum work function of a metal so that it can emit light will be equal to energy absorbed by these light to change the transition state from n=1 to n=2

So maximum work function can be

The light emitted in the transition n = 3 to n = 2 in hydrogen is called Hα light. Find the maximum work function a metal can have so that Hα light can emit photoelectrons from it.
