Question

Match the temperature of a black body given in List-I with an appropriate statement in List-II, and choose the correct option.
[Given: Wien’s constant as $2.9 \times 10^{−3} m^{-K}$ and $\frac{hc}{e} = 1.24 \times 10^{−6} V^{-m}$]

List-I	List-II
(P)	2000 K
(Q)	3000 K
(R)	5000 K
(S)	10000 K
	(5)

• A. P$\rightarrow$3, Q$\rightarrow$5, R $\rightarrow$2, S$\rightarrow$3
• B. P$\rightarrow$3, Q$\rightarrow$2, R$\rightarrow$4, S$\rightarrow$1
• C. P$\rightarrow$3, Q$\rightarrow$4, R$\rightarrow$2, S$\rightarrow$1
• D. P$\rightarrow$1, Q$\rightarrow$2, R$\rightarrow$5, S$\rightarrow$3

Answer 1

Answer: (C)

P$\rightarrow$3, Q$\rightarrow$4, R$\rightarrow$2, S$\rightarrow$1

Answer 2

The correct option is (C): P$\rightarrow$3, Q$\rightarrow$4, R$\rightarrow$2, S$\rightarrow$1
