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

Answer»

`(5RC)/(36)`
`(8RC)/(9)`
`(R C)/(25)`
`(3RC)/(27)`

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