The maximum wavelength of radiation emit...

The maximum wavelength of radiation emitted at 200 K is 4 μm. What will be the maximum wavelength of radiation emitted at 2400 K ?

A

`3mum`

B

`0.3mum`

C

`2mum`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
As, `lambda_(2)/lambda_(1) = T_(1)/T_(2) rArr lambda_(2) = T_(1)/T_(2) xx lambda_91) = (900)/1200 xx 4 = 3mum`
