The energy of photon of reddish light having wavelength 660nm is (`h=6.6xx10^(-34)Js`)

A

`1xx10^(-19)J`

B

`3.0xx10^(-18)J`

C

`1xx10^(19)J`

D

`3.0xx10^(-19)J`

Text Solution

Verified by Experts

The correct Answer is:
D
`E=(hc)/(lamda)=(6.6xx10^(-34)xx3.0xx10^(8))/(66.xx10^(-9))`
`=3.0xx10^(19)J`
