Correct Answer is : P→3,Q→4,R→2,S→1

{\P} \to 3, {\Q} \to 5, {\R} \to 2, {\S} \to 3

\P \to 3, \Q \to 2, \R \to 4, \S \to 1

\P \to 3, \Q \to 4, \R \to 2, \S \to 1

\P \to 1, \Q \to 2, \R \to 5, \S \to 3

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 2.9×10−3m−K and ‌

=1.24×10−6V−m ]

List-I	List-II
(P) 2000K	(1) The radiation at peak wavelength can lead to emission of photoelectrons from a metal of work
(Q) 3000K	(2) The radiation at peak wavelength is visible to human eye.
(R) 5000K	(3) The radiation at peak emission wavelength will result in the widest central maximum of a single slit diffraction.
(S) 10000K	(4) The power emitted per unit area is 1/16 of that emitted by a blackbody at temperature 6000K.
	(5) The radiation at peak emission wavelength can be used to image human bones.
