Answer:
(a) The work function is 1.86 eV. 
(b) The cut off frequency is 450 THz. 
(c) The stopping potential is 1.16 V. 
Explanation:
incident wavelength = 620 nm 
Kinetic energy, K = 0.14 eV 
According to the photoelectric equation 
E = W + KE 
where, W is the work function, KE is the kinetic energy. 
(a) Let the work function is W. 
 
(b) Let the cut off frequency is f. 
W = h f 

(c) Let the stopping potential is V.
