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

A

4000 Å

B

5000 Å

C

6000 Å

D

3000 Å

Text Solution

Verified by Experts

The correct Answer is:
D
`(lambda_(1))/(lambda_(2))=(T_(2))/(T_(1))`
`(5000 Å)/(lambda_(2))=(2500 K)/(1500 K)`
`lambda_(1)=3000 Å`
