Solar radiation emitted by sun resembles that emitted by a body at a temperature of `6000 K` Maximum intensity is emitted at a wavelength of about `4800A^(@)` If the sun was cooled down from `6000K` to `3000K` then the peak intensity would occure at a wavelenght of .

A

4800 Å

B

9600 Å

C

7200 Å

D

6400 Å

Text Solution

Verified by Experts

The correct Answer is:
B
`lamda_(m_(2))=(lamda_(m_(1))T_(2))/(T_(1))=(4800xx6000)/(3000)=9600A^(@)`.
