Question

Two stars emit maximum radiation at wavelength $3600\text{Å}and4800\text{Å}$ respectively. The ratio of their temperatures is

• A. 1 : 2
• B. 3 : 4
• C. 4 : 3
• D. 2 : 1

Answer 1

The correct option is C

4 : 3

$\frac{T_1}{T_2}=\frac{{\lambda }_{m_2}}{{\lambda }_{m_1}}=\frac{4800}{3600}\Rightarrow \frac{48}{36}=\frac{4}{3}$
