The electromagnetic (EM) spectrum is the range of all types of EM radiation. … The other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light, ultraviolet light, X-rays and gamma-rays.
What are the 7 types of electromagnetic spectrum?
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. …

How do we use the electromagnetic spectrum in everyday life?
Everyday life is pervaded by artificially made electromagnetic radiation: food is heated in microwave ovens, airplanes are guided by radar waves, television sets receive electromagnetic waves transmitted by broadcasting stations, and infrared waves from heaters provide warmth.
Which color has the highest 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. They range from around a foot long to several miles long.
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.
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?
Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency.23 мая 2019 г.
What are 3 properties of electromagnetic waves?
Every form of electromagnetic radiation, including visible light, oscillates in a periodic fashion with peaks and valleys, and displaying a characteristic amplitude, wavelength, and frequency that defines the direction, energy, and intensity of the radiation.
What are the importance of electromagnetic waves?
Electromagnetic waves are used to transmit long/short/FM wavelength radio waves, and TV/telephone/wireless signals or energies. They are also responsible for transmitting energy in the form of microwaves, infrared radiation (IR), visible light (VIS), ultraviolet light (UV), X-rays, and gamma rays.
What are examples of waves in our daily lives?
Waves in Everyday Life
Sound is a type of wave that moves through matter and then vibrates our eardrums so we can hear. Light is a special kind of wave that is made up of photons. You can drop a rock into a pond and see waves form in the water. We even use waves (microwaves) to cook our food really fast.
What causes the electromagnetic spectrum?
EM radiation is created when an atomic particle, such as an electron, is accelerated by an electric field, causing it to move. The movement produces oscillating electric and magnetic fields, which travel at right angles to each other in a bundle of light energy called a photon.
