Question
An electron in a hydrogen like atom makes transition from a state in which its de-Broglie wavelength isλ1 to a state where its de-Broglie wavelength is λ2 then wavelength of photon (λ) generated will be
where m is mass of the electron, c is speed of light in vaccum.
where m is mass of the electron, c is speed of light in vaccum.
Options
A.λ = λ1 - λ2
B.λ = 
C.λ = 
D.λ = 
Solution
= E1 - E2 = KE2 - KE1∴ λ =
(mV)2 = 
; 
mV2 = 
∴
. ∴ λ =
