If the light from Balmer series of hydrogen is used to eject photoelectrons from a metal then the maximum work-function of the metal can be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
In Balmer series, 
will be maximum when 
is 
So, 
So this can be maximum energy of photon. So metal can have work function of maximum 
.
