Question

Match List - I with List - II.

List I (Electromagnetic waves)		List II (Wavelength)
a	AM radio waves	i	$10^{-10}m$
b	Microwaves	ii	$10^{2}m$
c	Infrared radiations	iii	$10^{-2}m$
d	X - rays	iv	$10^{-4}m$

Choose the correct answer from the options given below:

• A. (a) - (ii), (b) - (iii), (c) - (iv), (d) - (i)
• B. (a) - (iv), (b) - (iii), (c) - (ii), (d) - (i)
• C. (a) - (iii), (b) - (ii), (c) - (i), (d) - (iv)
• D. (a) - (iii), (b) - (iv), (c) - (ii), (d) - (i)

Answer 1

Answer: (A)

(a) Radio wave (ii) $\approx 10^{2}m$ (ii)
(b) Microwave $\approx$ (iii) $10^{-2}m$ (iii)
(c) Infrared radiations $\approx (iv)10^{-4}m$ (iv)
(d) X-ray (i) $\approx \mathring{A}=10^{-10}m$ (i)
(a) - (ii), (b) - (iii), (c) - (iv), (d) - (i)
