JEE MAIN - Physics (2020 - 5th September Evening Slot - No. 14)
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 |
(a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)
(a)-(iv), (b)-(ii), (c)-(i), (d)-(iii)
(a)-(iii), (b)-(ii), (c)-(i), (d)-(iv)
(a)-(i), (b)-(iii), (c)-(iv), (d)-(ii)
Explanation
Decreasing order of wavelength,
Radio wave > Microwave > Infrared > ROYGBIV(Visiable Resion) > Ultraviolet > X rays > $$\gamma $$ rays
$$ \therefore $$ Correct order is
(a)-(iv), (b)-(ii), (c)-(i), (d)-(iii)
Radio wave > Microwave > Infrared > ROYGBIV(Visiable Resion) > Ultraviolet > X rays > $$\gamma $$ rays
$$ \therefore $$ Correct order is
(a)-(iv), (b)-(ii), (c)-(i), (d)-(iii)
