The correct match between the entries in
column I and column II are :
| I | II |
|---|---|
| Radiation | Wavelength |
| (a) Microwave | (i) 100 m |
| (b) Gamma rays | (ii) 10–15 m |
| (c) A.M. radio waves | (iii) 10–10 m |
| (d) X-rays | (iv) 10–3 m |
Solution
Decreasing order of wavelength,
<br><br>Radio wave > Microwave > Infrared > ROYGBIV(Visiable Resion) > Ultraviolet > X rays > $\gamma$ rays
<br><br>$\therefore$ Correct order is
<br><br>(a)-(iv), (b)-(ii), (c)-(i), (d)-(iii)
