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.

Text Solution

Verified by Experts

According to Wien's displacement law, we have
`lamda_(m)=T=` constant
or `lamda_(m1)T_1=lamda_(m2)T_2`
Thus `20000xx10^-10xx1500=5500xx10^-10xxT_2`
or `T_2=(200)/(55)xx1500=5454.54`K
