A black body at `1227^(@)C` emits radiations with maximum intensity at wavelength of 5000 `Å`. If temperature of the body is increased by `1000^(@)C`, the maximum intensity will be observed at :

A

`3000Å`

B

`4000Å`

C

`5000Å`

D

`6000Å`

Text Solution

Verified by Experts

The correct Answer is:
A

`lamda_(1,)T_(1)=lamda_(2m)T_(2)`
`lamda_(2,)=(lamda_(1m)*T_(1))/(T_(2))=(5000xx1500)/(2500)=3000Å`
Correct choice is (a).
