Question

Which example is NOT a part of the electromagnetic spectrum?

Answer 1

Electricity is NOT a part of electromagnetic spectrum.

An electromagnetic spectrum contains electromagnetic radiations arranged according to frequencies and wavelength.

Further Explanation

Electromagnetic waves  

• Electromagnetic waves are types of waves that do not require a material medium for transmission.
• These waves are mostly transverse in nature, which means the direction of transmission is perpendicular to the direction of vibration of particles.
• They include, light waves, radio waves, x-rays, infra-red, etc.

Electromagnetic spectrum

• An electromagnetic wave shows electromagnetic waves arranged according to frequencies and wavelength.  
• Electromagnetic spectrum contains electromagnetic waves: Gamma rays, x-rays, Ultraviolet, Visible light, infra-red, microwaves, and radio waves.
• The electromagnetic spectrum is divided into various sections based on wavelength, with gamma rays having the shortest wavelength and radio waves having the longest wavelength.
• The part of the electromagnetic spectrum that we can see using our naked eyes is called the visible light spectrum.
• In order of frequency, the radio waves have the lowest frequency while gamma rays have the largest frequency.

General characteristics of electromagnetic waves  

• They travel with the speed of light (3.0 x 10^8 m/s)
• They possess energy that is given by; E =hf, where h is the plank’s constant and f is the frequency.
• They are transverse in nature, and therefore, the wavelength is measured between successful crests or troughs.
• They can travel through vacuum

Answer 2

Explanation :

The electromagnetic spectrum shows the wavelength or frequency range of any wave.

It consists of the following waves :

• Gamma rays (short wavelength or high frequency)
• X-rays
• Ultraviolet rays
• Visible light
• Infrared rays
• Microwaves
• Radio waves (long wavelength or short frequency)

So, the purple light is not the part of the electromagnetic spectrum.

Hence, the correct option is (c).
