Light from balmer series of hydrogen is ...

Light from balmer series of hydrogen is able to eject photoelectron from a metal what can be the maximum work function of the metal?

Text Solution

Verified by Experts

The correct Answer is:
C, D
The maximum energy liberated by the Balmer Series is
`n_1=2`, `n_1=oo`
`E=13.6((1)/(n_1^2)-(1)/(n_2^2))`
`=13.6 xx 1/4 = 3.4 eV`
`3.4 eV is the maximum work function of the metal
