Excited hydrogen atom emits light in the...

Excited hydrogen atom emits light in the ultra violet region at `2.47 xx 10^(15)` Hz. With this frequency, the energy of a single photon is (Given: `h = 6.63 xx 10^(-34) J s`)

A

`8.041 xx 10^(-40)J`

B

`2.680xx10^(-19)J`

C

`1.640xx10^(-18)J`

D

`6.111 xx 10^(-17)J`

Text Solution

Verified by Experts

The correct Answer is:
C

`E=hv =(6.63xx10^(-34)Js) (2.47xx10^(15)s^(-1))=1.64xx10^(-18)J`
