What are the types of electromagnetic waves and their uses?
Behaviour and uses of electromagnetic wavesRadio waves.
Radio waves are used for communication such as television and radio.
Microwaves are used for cooking food and for satellite communications.
Where are the best waves?

What are the 2 types of waves?
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.
How do waves behave?
Light waves across the electromagnetic spectrum behave in similar ways. When a light wave encounters an object, they are either transmitted, reflected, absorbed, refracted, polarized, diffracted, or scattered depending on the composition of the object and the wavelength of the light.
What is a wave made of?
Mechanical waves are caused by a disturbance or vibration in matter, whether solid, gas, liquid, or plasma. Matter that waves are traveling through is called a medium. Water waves are formed by vibrations in a liquid and sound waves are formed by vibrations in a gas (air).
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 type of waves are sound waves?
Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves. A vibrating string can create longitudinal waves as depicted in the animation below.
What are the 3 types of sound?
Types of Waves. So what type of wave is sound? Sound waves fall into three categories: longitudinal waves, mechanical waves, and pressure waves. Keep reading to find out what qualifies them as such.
What is a scalar wave?
A scalar wave (hereafter SW) is just another name for a “longitudinal” wave. The term scalar is sometimes used instead because the hypothetical source of these waves is thought to be a “scalar field” of some kind, similar to the Higgs field for example.
What are 3 types of wave mediums?
The matter through which a mechanical wave travels is called the medium (plural, media). There are three types of mechanical waves: transverse, longitudinal, and surface waves. They differ in how particles of the medium move when the energy of the wave passes through.
What types of waves exist?
Based on the orientation of particle motion and direction of energy, there are three categories: Mechanical waves. Electromagnetic waves….Electromagnetic WaveMicrowaves.X-ray.Radio waves.Ultraviolet waves.
What is the difference between a pulse and a wave?
A pulse refers to a disturbance that travel from one location to another location through a medium. While, A wave refers to the disturbance or variation that travels through the medium. … A pulse is actually a disturbance made up of a very large number of waves of different frequencies.
Can radio waves kill you?
According to experts on the biological effects of electromagnetic radiation, radio waves become safer at higher frequencies, not more dangerous. (Extremely high-frequency energies, such as X-rays, behave differently and do pose a health risk.)
What do you mean by wave?
A wave is a physical phenomenon characterized by its frequency, wavelength, and amplitude. In general, waves transfer energy from one location to another, in which case they have a velocity. … Longitudinal waves, such as sound, oscillate parallel to the direction of energy transfer.
Do humans emit electromagnetic waves?
Yes, all objects, including human bodies, emit electromagnetic radiation. The wavelength of radiation emitted depends on the temperature of the objects. Such radiation is sometimes called thermal radiation. Most of the radiation emitted by human body is in the infrared region, mainly at the wavelength of 12 micron.
What causes a wave?
Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. … The gravitational pull of the sun and moon on the earth also causes waves.
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.
How many types of waves are there in physics?
twoThere are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves. The animations below demonstrate both types of wave and illustrate the difference between the motion of the wave and the motion of the particles in the medium through which the wave is travelling.
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. … X-rays: Penetrating Radiation. … Gamma Rays: Nuclear Energy.
What type of waves are light waves?
Light waves move as transverse waves (see diagram of a transverse wave) and can move through a vacuum (empty space) at a speed of approximately 186,000 miles per second. Light has both magnetic and electric fields. Scientists call this electromagnetic radiation (light).
What wavelengths are dangerous?
Ultraviolet (UV) (Wavelength 10-7 – 10-8 meters) UV-C rays are the most harmful and are almost completely absorbed by our atmosphere. UV-B rays are the harmful rays that cause sunburn.
