What is meant by electromagnetic wave?
Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. Description: Electromagnetic waves are formed when an electric field comes in contact with a magnetic field. They are hence known as ‘electromagnetic’ waves.
What are 10 examples of electromagnetic waves?

How do electromagnetic waves travel?
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space. This proved that radio waves were a form of light!
What is the best definition of high electromagnetic energy?
Electromagnetic energy is a form of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space.
Which type of wave travels the fastest?
P waves
P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.
What are the 2 main types of waves?
Types and features 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.
Do electromagnetic waves lose energy?
An EM wave can travel without a material medium—that is, in a vacuum or space empty of matter—and does not lose energy as it moves. In theory, an EM wave can travel forever. Because they do not need a medium, EM waves can pass through outer space, which is a near vacuum.
What are electromagnetic waves have the highest energy?
Electromagnetic waves have an extremely wide range of wavelengths, frequencies, and energies. The highest energy form of electromagnetic waves are gamma (γ) rays and the lowest energy form are radio waves. The figure below shows the electromagnetic spectrum, which is all forms of electromagnetic radiation.
What are the four properties of electromagnetic waves?
The Four Properties Of Electromagnetic Waves Are As Follows – 1)Electromagnetic Waves Are Propagated By Oscillating Electric Field And Magnetic Field At Right Angles To Each Other. 2) Electromagnetic Waves Are Transverse Waves And Do Not Need A Medium To Propagate. 3) Electromagnetic Waves Can Be…
What are the names of the electromagnetic waves?
The electromagnetic spectrum is made up of six different types of waves. Radio waves, Microwaves, Infrared waves, Visible light, Ultraviolet light, X-rays and Gamma rays.
What are electromagnetic waves have the highest frequency?
Gamma rays have the highest frequency. Explanation: There are seven regions in the electromagnetic spectrum which in order of lowest to highest frequency are: Radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays.
