1.	The surface temperature of the sun which has maximum energy emission at 500nm is 6000K. The temperature of a star which has maximum energy emission at 400nm will be
Answer» 8500K 4500K 7500K 6500K Solution :By Wien.s displacement LAW, `lamda_(m)T`= constant `:. lamda_(m)T= lamda._(m) T. or 500 XX 6000 = 400 xx T.` or `T.= (500 xx 6000)/(400) = 7500K`
