A gas absorbs photon of 355 nm and emits at two wavelengths. If one of the emission is at 680 nm, the other is at

A

`1035 nm`

B

`325 nm`

C

`743 nm`

D

`518 nm`

Text Solution

Verified by Experts

The correct Answer is:
3
`E=E_(1)+E_(2)`
`(hc)/lambda=(hc)/lambda_(1)+(hc)/lambda_(2)rArr " "1/lambda=1/lambda_(1)+1/lambda_(2)rArr " " 1/355=1/680+1/lambda_(2)`
`lambda_(2)=742.76 nm`
