This range is known as 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.
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 7 electromagnetic waves in order from lowest to highest frequency?
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 the 7 types of electromagnetic waves and their uses?
Though the sciences generally classify EM waves into seven basic types, all are manifestations of the same phenomenon.
- Radio Waves: Instant Communication. …
- Microwaves: Data and Heat. …
- Infrared Waves: Invisible Heat. …

What is the correct order of types of electromagnetic radiation?
In order of increasing frequency and decreasing wavelength these are: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
What is the most important electromagnetic wave?
The most important of these is visible light, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves. They range from around a foot long to several miles long.
What are 3 examples of electromagnetic energy?
- Radio Waves.
- TV waves.
- Radar waves.
- Heat (infrared radiation)
- Ultraviolet Light (This is what causes Sunburns)
- X-rays (Just like the kind you get at the doctor’s office)
- Short waves.

Can electromagnetic waves harm you?
There is no doubt that short-term exposure to very high levels of electromagnetic fields can be harmful to health. … Despite extensive research, to date there is no evidence to conclude that exposure to low level electromagnetic fields is harmful to human health.
What types of waves exist?
Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.
What do all electromagnetic waves have in common?
All electromagnetic waves have two wavefronts, which are an oscillating electric field and an oscillating magnetic field.
What is the correct order of increasing energy?
For the entire electromagnetic spectrum, the correct order of all the radiation types by increasing energy (which means an increasing frequency and decreasing wavelength) is as follows: radio waves. microwaves. infrared.
