The spectral energy distribution of the sun has a maximum at `4754Å`. If the temperature of the sun is 6050 K, what is the temperature of a star for which this maximum is at `9506Å`?

Answer

`[3025 K]`

Explanation

Here, `T_(1)=6050 K, lambda_(1) =4753 Å`,
`T_(2)= ?`
From Wien's Displacement law
`lambda_(1) T_(1)=lambda_(2) T_(2)=` a constant
or `T_(2)=(lambda_(1)T_(1))/(lambda_(2))=(4753xx6050)/(9506) =3025 K`
