The energy of photon in watt hour for electromagnetic waves of wavelength 3000 Å, is `("Given, h=6.6 "xx 10^(-34)Js)`

A

`1.00 xx 10^(-25)Wh`

B

`1.83 xx 10^(-22)Wh`

C

`2.09 xx 10^(-23)Wh`

D

`4.05 xx 10^(-22)Wh`

Text Solution

Verified by Experts

The correct Answer is:
B
`E=(hc)/lambda=6.6 xx 10^(-19)J (Ws)=(6.6 xx 10^(-19))/(60 xx 60)=1.83 xx 10^(-22)Wh`
