## What does the electromagnetic spectrum not include?

Electromagnetic spectrum consists of radio waves, microwaves, infrared waves, visible spectrum, ultraviolet waves, X-rays and gamma rays. It does not include alpha rays.

## Which rays are not the portion of electromagnetic spectrum?

So, correct answer is option (C), i.e α rays.

Which is not a type of electromagnetic wave?

Beta rays are not electromagnetic waves because they are charged particles and are capable of getting deflected by the magnetic field. These rays are not pure energy as a photon.

### Which rays are portion of electromagnetic spectrum?

In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.

### What are all the rays in the electromagnetic spectrum?

Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.

How many types of waves are in the electromagnetic spectrum?

7 Types of Electromagnetic Waves

• Radio Waves: Instant Communication. •••
• Microwaves: Data and Heat. •••
• Infrared Waves: Invisible Heat. •••
• Visible Light Rays. •••
• Ultraviolet Waves: Energetic Light. •••
• Gamma Rays: Nuclear Energy. •••

## What are the 7 types of electromagnetic waves?

The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.

## What are the three regions of the electromagnetic spectrum?

λ is the wavelength

• ν is the frequency
• E is the energy
• c is the speed of light,c = 299,792,458 m/s (186,212 miles/second)
• h is Planck’s constant,h = 6.626 x 10 -27 erg-seconds
• What are the parts of the electromagnetic spectrum?

The entire electromagnetic spectrum, from the lowest to the highest frequency (longest to shortest wavelength), includes all radio waves (e.g., commercial radio and television, microwaves, radar ), infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

### What is the Order of the electromagnetic spectrum?

The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays. See full answer to your question here.
