If the electron in an hydrogen atom jumps from an orbit with level `n_(f) = 3` to an orbit with level `n_(f) = 2`, the emitted rediation has a wavelength given by

Options

A. `lambda = (R )/(6)`
B. `lambda = (R )/(6)`
C. `lambda = (36)/(5R)`
D. `lambda = (5R)/(36)`

Answer

C

Explanation

`(1)/(lambda) = R((1)/(n_1^2) -(1)/(n_2^2)) = R ((1)/(4) - (1)/(9)) = (5R)/(36)`
`:. Lambda = (36)/(5R).`
