Question

Three stars A,B,C have surface temperatures T $_{A}$ ,T $_{B}$ and T $_{C}$ . A appers bluish , B apears reddish and C appears yellowish. We can conclude that.

Open in App

Solution

We know that-

$λ T = c o n s t a n t$

$⟹ λ \propto \frac{1}{T}$

$λ_{A} < λ_{C} < λ_{B}$

Hence, $T_{A} > T_{C} > T_{B}$

Three stars A,B,C have surface temperatures TA,TB and TC. A appers bluish , B apears reddish and C appears yellowish. We can conclude that.

We know that-λT=constant⟹λ∝1TλA<λC<λBHence, TA>TC>TB
