If, an electron in hydrogen atom jumps from an orbit of lelvel n=3 to an orbit of level n=2, emitted radiation has a freqwuency (R= Rydbertg's contant ,c = velocity of light)

A

`(Rc)/(25)`

B

`(5Rc)/(36)`

C

`(3Rc)/(27)`

D

`(8Rc)/(9)`

Text Solution

Verified by Experts

The correct Answer is:
B
`f= Rc ((1)/(n_(1)^(2))- (1)/(n_(2)^(2)))= Rc ((1)/(2^(2))- (1)/(3^(2))) = (5Rc)/(36)`
