Photoelectric EffectHard
Question
If a hydrogen atom at rest, emits a photon of wavelength λ, the recoil speed of the atom of mass m is given by :
Options
A.
B.
C.mhλ
D.none of these
Solution
P = const = 
photon + atom = 0
∵ λ =
⇒ v = 
photon + atom = 0∵ λ =
⇒ v = Create a free account to view solution
