1.	The spectral energy distribution of the sun has maxima at 4753 Å. Find the temperature of a star for which spectral distribution has maxima at 10350 Å. [Temperature of sun is 6000 K]
Answer» SOLUTION :According to Wien's displacement LAW `lambda_(m) alpha1/T` `THEREFORE lambda_(2)/lambda_(1)=T_(1)/T_(2) rArrT_(2)=T_(1)lambda_(1)/lambda_(2)` `RARR T_(2) = 6000 xx 4753/10350` `rArr T_(2)=2755.4 `K
