Match List-I with List-II
List-I (Electromagnetic waves):
(a) AM radio waves
(b) Microwaves
(c) Infrared radiations
(d) X-rays
List-II (Wavelength):
(i) $10^{-10}$ m
(ii) $10^{2}$ m
(iii) $10^{-2}$ m
(iv) $10^{-4}$ m
Choose the correct answer from the options given below
Answer: (A) (a) - (ii), (b) - (iii), (c) - (iv), (d) - (i)
Typical wavelengths, from longest to shortest:
AM radio waves: hundreds of metres, $10^2$ m (ii).
Microwaves: millimetres to centimetres, $10^{-2}$ m (iii).
Infrared: around $10^{-4}$ m to $10^{-6}$ m, so $10^{-4}$ m (iv).
X-rays: about $10^{-10}$ m (i).
(a)-(ii), (b)-(iii), (c)-(iv), (d)-(i).
