Given Rydberg costant R = 10^(5)cm^(-1)....

Given Rydberg costant` R = 10^(5)cm^(-1)`. Supposing if electron jumps from M shell to K shell of H - atom, the frequency of the radiation emitted in cycle/s would be :-

A

`(8)/(9)xx10^(5)`

B

`(8)/(3)xx10^(15)`

C

`(8)/(3)xx10^(11)`

D

`(8)/(9)xx10^(15)`

Text Solution

Verified by Experts

The correct Answer is:
B

`u=RCZ^(2)((1)/(1^(2))-(1)/(3^(2)))`
`=10^(7)xx3xx10^(8)xx(8)/(9)=(8)/(3)xx10^(15)`
