X-rays – Gamma rays – UV – Infrared – Visible – Microwaves – Radio and TV waves
Gamma rays – X-rays – UV – Infrared – Visible – Microwaves – Radio and TV waves

The electromagnetic spectrum is the range of all types of electromagnetic radiation. These radiations differ in wavelength, frequency, and energy. The question asks for the order of regions of the spectrum in terms of ascending (increasing) wavelength.
The order of the electromagnetic spectrum from shortest wavelength (highest frequency/energy) to longest wavelength (lowest frequency/energy) is:
Gamma rays → X-rays → Ultraviolet (UV) → Visible light → Infrared (IR) → Microwaves → Radio waves.
We need to arrange the given options in increasing wavelength.
Let’s check option C: Gamma rays – X-rays – UV – Visible – Infrared – Microwaves – Radio and TV waves. This sequence correctly lists the regions from shortest wavelength (Gamma rays) to longest wavelength (Radio waves). TV waves are a type of radio wave.
Comparing this with the other options, none of them follow the correct order of increasing wavelength.
