A black body at 1500K emits maximum energy of wavlength 20000`Å`. If sun emits maximum energy of wavelength `5500Å`, what would be the temperature of sun.

Verified by Experts

According to Wein's displacement law, we have
`lambda_(m)T = constant`
or `lambda_(m1)T_(1) = lambda_(m2)T_(2)`
Thus `20000 xx 10^(-10) xx 1500`
`=5500 xx 10^(-10) xx T_(2)`
or `T_(2) =(200)/(55) xx 1500`
=5454.54K
