Question

Match List-I with List-II :-

	List-I (EM-Wave)		List-II Wavelength Range
(A)	Infra-red	(I)	< 10–3 nm
(B)	Ultraviolet	(II)	400 nm to 1 nm
(C)	X-rays	(III)	1 mm to 700 nm
(D)	Gamma rays	(IV)	1 nm to 10–3 nm

Choose the correct answer from the options given below :

(1) (A)-(II), (B)-(I), (C)-(IV), (D)-(III) 

(2) (A)-(III), (B)-(II), (C)-(IV), (D)-(I) 

(3) (A)-(IV), (B)-(III), (C)-(II), (D)-(I) 

(4) (A)-(I), (B)-(III), (C)-(II), (D)-(IV)

Answer 1

Correct option is : (2) (A)-(III), (B)-(II), (C)-(IV), (D)-(I)

Infrared is the least energetic thus having biggest wavelength \((\lambda) \ \&\) gamma rays are most energetic thus having smallest wavelength \((\lambda)\).
