The wave number of a spectral line is 5x...

The wave number of a spectral line is `5xx10^(5)m^(-1)`. The energy corresponding to this line is

A

`3.49xx10^(-23)` kJ

B

`4.45xx10^(-24)` J

C

`5.50xx10^(-22)` J

D

`9.93xx10^(-23)` kJ

Text Solution

Verified by Experts

The correct Answer is:
D

Energy `E=(hc)/lambda = hc barv`
`=6.62xx10^(-34)xx3xx10^(8)xx5xx10^(5)(barv=1/lambda)`
`=9.93xx10^(-23)` kj
