The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.
What are the 6 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 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. …
- Visible Light Rays. …
- Ultraviolet Waves: Energetic Light. …

What are 5 examples of electromagnetic radiation?
- 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.
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.
Is current an electromagnetic wave?
2 Answers. Electric current is the movement of electric charge through a conductor. … Electromagnetic waves are created by moving electric charges, but once created, they can propagate through a vacuum. Photons are the smallest packets of energy that propagate as electromagnetic waves.
What color has highest frequency?
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.
How do you identify radiation type?
To determine the type of radiation (alpha, beta or gamma), first determine the background count rate, then the source count rate with no absorber. Next, place a sheet of paper between the source and the monitor. If the counts are significantly reduced, the source emits alpha particles.
What types of radiation are not harmful?
Alpha, beta, and gamma rays also cause damage to living matter, in varying degrees. Alpha particles have a very small absorption range, and thus are usually not harmful to life, unless ingested, due to its high ionizing power.
Which type of radiation has the highest energy?
What electromagnetic wave is the most dangerous?
What uses electromagnetic energy?
Up to the end of the microwave spectrum, most all modern conveniences that use electromagnetic energy in one way or another are in the lower frequency region, including millimeter waves, cell phones, WiFi, microwave ovens, space and terrestrial communications, radar for airports and military uses, AM and FM radio, …
Why is it called an electromagnetic wave?
The waves of energy are called electromagnetic (EM) because they have oscillating electric and magnetic fields. … If it has low frequency, it has less energy and could be a TV or radio wave. All EM energy waves travel at the speed of light. No matter what their frequency or wavelength, they always move at the same speed.
