An electron jumps from 5th orbit to 4th ...

An electron jumps from `5th` orbit to `4th` orbit of hydrogen atom. Taking the Rydberg constant as `10^(7)` per meter. What will be the frequency of radiation emitted ?

A

`6.75 xx 10^(12) Hz`

B

`6.75 xx 10^(14) Hz`

C

`6.75 xx 10^(13) Hz`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
By using `v = RC [(1)/(n_(1)^(2)) - (1)/(n_(2)^(2))]`
`rArr v = 10^(7) xx (3 xx 10^(8)) [(1)/(4^(2)) - (1)/(5^(2))] = 6.75 xx 10^(13) Hz`
