The wavelength of maximum emitted energy...

The wavelength of maximum emitted energy of a body at 700 K is `4.08 mu m`. If the temperature of the body is raised to 1400 K , the wavelength of maximum emitted energy will be

A

`1.02 mum`

B

`16.32mum`

C

`8.16mum`

D

`2.04mum`

Text Solution

Verified by Experts

The correct Answer is:
D
`lamda_(m_(1))T_(1)=lamda_(m_(2))T_(2)`
`therefore lamda_(m_(2))=(lamda_(m_(1))T_(1))/(T_(2))=4.08xx(700)/(1400)=2.04`m
