The work function ( 
) of the some metals is listed below.
(i) 
(ii) 
(iii) 
(iv) 
(v) 
(vi) Ag, 
(vii) 
The number of metals which will show photoelectric effect, when light of 300 nm wavelength falls on the metal is
Text Solution
Verified by ExpertsThe correct answer is:
B
As, energy of photon 
To show photoelectric effect, energy of incident photons must be greater than work function of metal. Thus, among the given metals, only four, i.e. (i), (ii), (iii) and (iv) will show photoelectric effect.
