The light emitted in the transition 
to 
(where 
is the principal quantum number of the state) in hydrogen is called 
-light. Find the maximum work function that a metal can have so that 
-light can emit photoelectrons from it.
A

C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
So, if work function is greater than 
will not do photo-emission.
So, 
is the maximum work function of metal for photo-emission.
