Electromagnetic Waves

JEE Main level, single correct, medium

151 of 165

Question 151 of 165

If microwaves, $X‐$ rays, infrared, gamma rays, ultraviolet, radio waves and visible parts of the electromagnetic spectrum are denoted respectively by $M$ , $X$ , $I$ , $G$ , $U$ , $R$ and $V$ the following is the arrangement in ascending order of the wavelength

Show answer and solution

Answer: (D) $G$ , $X$ , $U$ , $V$ , $I$ , $M$ and $R$

The electromagnetic (EM) spectrum is the range of all types of EM radiation. The

\gamma ‐

ray has a maximum frequency or minimum wavelength; since the wavelength is inversely proportional to frequency, while radio wave has a minimum frequency and maximum wavelength. The order of wavelength will be; Gamma rays

G

< X-rays

X

< Ultra violet

U

< Visible rays

V

< Infrared rays

I

< Microwaves

M

< Radio waves

R
