Question
Cut potential for metal photoelectric effect for light of wavelength λ1, λ2 and λ3 will be
Options
A.Arithmetic progression
B.Geometric progression
C.Harmonic Progression
D.None
Solution
eV1 = 
- 
,eV2 = 
- 
, eV3 = 
- 
if 2V2 = V1 + V3 ⇒
harmonic progression
- ,eV2 = - , eV3 = - if 2V2 = V1 + V3 ⇒
harmonic progression
