Step-by-Step Solution

The wavelength ranges for the given electromagnetic waves are roughly:

  1. AM Radio Waves: These have long wavelengths, typically in the range of hundreds of meters (>100 m> 100 \text{ m}). Thus, they correspond to 102 m10^2 \text{ m}. -> (a) matches (ii).
  2. Microwaves: These range from millimeters to centimeters (10−3 m10^{-3} \text{ m} to 10−1 m10^{-1} \text{ m}). Thus, they correspond to 10−2 m10^{-2} \text{ m}. -> (b) matches (iii).
  3. Infrared Radiation: These are shorter than microwaves but longer than visible light, typically 10−3 m10^{-3} \text{ m} to 7×10−7 m7 \times 10^{-7} \text{ m}. Thus, they correspond to 10−4 m10^{-4} \text{ m}. -> (c) matches (iv).
  4. X-rays: These have very short wavelengths, typically 10−8 m10^{-8} \text{ m} to 10−11 m10^{-11} \text{ m}. Thus, they correspond to 10−10 m10^{-10} \text{ m}. -> (d) matches (i).

Correct matching: (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i).
