Question
When a certain metallic surface is illumined with monochromatic light λ, the stopping for potential for photo electric current is 6V0. when same surface is illuminated with light of wavelength 2λ, the stopping potential is 2λ0. The threshold wavelength of this surface for photoelectric
Options
A.6λ
B.4λ / 3
C.4λ
D.8λ
⇒ 
=
