Electromagnetic Spectrum & Atmosphere

The correct match between the entries in column I and column II are:

Show answer and solution

Answer: (b)

Microwave: $\lambda \sim 10^{-3}\ \text{m}$ (iv).
Gamma rays: $\lambda \sim 10^{-15}\ \text{m}$ (ii).
AM radio waves: $\lambda \sim 100\ \text{m}$ (i).
X-rays: $\lambda \sim 10^{-10}\ \text{m}$ (iii).
So the answer is (b) (a)-(iv), (b)-(ii), (c)-(i), (d)-(iii).
