The energy of a photon corresponding to ...

The energy of a photon corresponding to the visible light of maximum wavelenth is approximately

A

1 eV

B

1.6 eV

C

7 eV

D

3 eV

Text Solution

Verified by Experts

The correct Answer is:
B
`E=hv=(hC)/(lambda_(max))`
`=(6.63xx10^(-34)xx3xx10^(8))/(7.6xx10^(-7)xx1.6xx10^(-19))=(19.89)/(12.16)~=1.6`
