Differbetween
The only difference between them is their wavelength, which is directly related to the amount of energy the waves carry. The shorter the wavelength of the radiation, the higher the energy. The rainbow of colors that we see in visible light represents only a very small portion of the electromagnetic spectrum.

Is radiation an electromagnetic wave?
Radiation — energy moving in the form of particles or waves. Familiar radiations are heat, light, radio waves, and microwaves. Ionizing radiation is a very high-energy form of electromagnetic radiation. Wavelength – Distance covered by one complete cycle of the electromagnetic wave.
What are the 7 types of electromagnetic radiation?
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 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. ...
- X-rays: Penetrating Radiation. ...
- Gamma Rays: Nuclear Energy.
Where do electromagnetic waves come from?
Description: Electromagnetic waves are formed when an electric field comes in contact with a magnetic field. They are hence known as 'electromagnetic' waves. The electric field and magnetic field of an electromagnetic wave are perpendicular (at right angles) to each other.
What are the 4 main properties of electromagnetic waves?
It depends on their properties. Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency.
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.
What do all electromagnetic waves have in common?
What do all electromagnetic waves have in common? They can travel at the speed of light. They have the same wavelengths. They travel only through matter.
What electromagnetic radiation is harmful?
Extreme ultraviolet and higher frequencies, such as X-rays or gamma rays are ionizing, and these pose their own special hazards: see radiation poisoning. The most common health hazard of radiation is sunburn, which causes between approximately 100,000 and 1 million new skin cancers annually in the United States.
What devices use electromagnetic waves?
Electromagnetic waves are ubiquitous in nature (i.e., light) and used in modern technology—AM and FM radio, cordless and cellular phones, garage door openers, wireless networks, radar, microwave ovens, etc. These and many more such devices use electromagnetic waves to transmit data and signals.
What are the 4 types of electromagnetic radiation?
The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays. To tour the electromagnetic spectrum, follow the links below!
What are the basic sources of electromagnetic waves?
Sources of Electromagnetic Radiation
- solar radiation, in other words natural radiation that originates from the sun.
- terrestrial radiation, in other words natural radiation emitted by the Earth's surface.
- artificial radiation originating from a remote sensing system.
