QJEEM20Ph0fe1: JEE Main 2020 Physics - Class 12 JEEM20Ph0fe1 Solution: The correct match between the entries in column I and column II …

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

Multiple Choice Options

  • A (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)
  • B (a)-(iv), (b)-(ii), (c)-(i), (d)-(iii)
  • C (a)-(iii), (b)-(ii), (c)-(i), (d)-(iv)
  • D (a)-(i), (b)-(iii), (c)-(iv), (d)-(ii)

Step-by-Step Verified Solution

Decreasing order of wavelength,

Radio wave > Microwave > Infrared > ROYGBIV(Visiable Resion) > Ultraviolet > X rays > γ\gamma rays

∴\therefore Correct order is

(a)-(iv), (b)-(ii), (c)-(i), (d)-(iii)
