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

3.2 eV

D

7 eV

Text Solution

Verified by Experts

The correct Answer is:
B
Energy of photon, `E=(12375)/(lamda("in Å"))eV`
for red light the wavelenth is maximum,
`because lamda_(R)=7900` Å
`therefore E=(12375)/(7900)eV=1.56eV=1.6eV`
