If an electron in hydrogen atom jumbs from an orbit of level n = 3 to an orbit of level n = 2, the emitted radiation has a frequency

Options

A. `(5RC)/(36)`
B. `(8RC)/(9)`
C. `(R C)/(25)`
D. `(3RC)/(27)`

Answer

A

Explanation

`gamma= RC ((1)/(n_(1)^(2))- (1)/(n_(2)^(2)))= RC ((1)/(2^(2))-(1)/(3^(2)))= RC ((1)/(4)- (1)/(9))= (5RC)/(36)`
