If the energy of photons corresponding to wavelength of 6000 Å is `3.2 xx 10^(-19) J`. The photon energy for wavelength of 4000 Å will be…..

A

`4.44 xx 10^(-19)J`

B

`2.22 xx 10^(-19)`J

C

`1.11 xx 10^(-19)J`

D

`4.80 xx 10^(-19)` J

Text Solution

Verified by Experts

The correct Answer is:
D
`E= (hc)/(lambda)`
`3.2 xx 10^(-19)= (hc)/(6000)implies hc= 6000 xx 3.2 xx 10^(-19)`
`E= (hc)/(lambda)= (6000)/(4000) xx 3.2 xx 10^(-19)= 4.8 xx 10^(-19) j`
