Question : What is the correct order of radiations in descending order of frequencies?
Option 1: Infrared > Microwaves > Radio waves > X-rays
Option 2: Radio waves > X-rays > Microwaves > Infrared
Option 3: X-rays > Infrared > Microwaves > Radio waves
Option 4: Infrared > Microwaves > X-rays > Radio waves
Correct Answer: X-rays > Infrared > Microwaves > Radio waves
Solution : The answer is X-rays > Infrared > Microwaves > Radio waves.
The electromagnetic (EM) spectrum is the range of all types of electromagnetic radiation organised by frequency or wavelength. The wave's frequency determines the type of electromagnetic radiation it radiates back. X-rays > Infrared > Microwaves > Radio waves are the correct radiations in descending order of frequencies.
