![]() ![]() Some of the important examples of electromagnetic waves are: Microwaves, Lightwaves, thermal radiation, X-rays, Radio waves and Ultraviolet waves The light and the colour that you see are due to the presence of electromagnetic waves. As in these waves, periodic changes take place in the magnetic fields they are called as electromagnetic waves.Įlectromagnetic waves are formed by the combination of magnetic and electric fields. In other words, electromagnetic waves travel from one place to another in a vacuum and at the same speed. ![]() In electromagnetic waves, there is no need for the presence of any medium for the propagation of the wave. Some of the examples of this type of longitudinal wave are sound waves, and pressure wave. It can also be put as the displacement of the medium occurs in the direction of the movement of the wave. There is a zero-degree angle formed between the wave particles and the energy particles. Here, the wave particles vibrate to and fro in the direction of the propagation of wave/ energy. This is another important variation of a wave. ![]() One of the best examples of transverse waves is radio waves, microwaves, ocean waves, wiggling string and polarized waves. In other words, when the energy particles and the wave particles form a perpendicular angle to each other, then it is called a transverse wave. In this type of wave, the medium vibrates to and fro at right angles to the direction of propagation of wave/energy. There are two types of Mechanical waves, as Transverse waves and Longitudinal waves It is seen in the form of waves breaking on the beach. When this factor increases from one, then it becomes the reason for turbulence. When the dimensionless factor is below one, it generates harmonic effects. Mechanical waves are measured by dividing displacement by the wavelength. Some of the examples of a mechanical wave are the “vibration of a string”, tsunami waves, earthquake waves, ultrasounds, waves in slink, oscillations in spring etc. There is no mass transfer possible during the movement of wave particles. Mechanical waves do not possess the ability to pass through the vacuum. In this type of wave, the entire disturbance that comprises of momentum and energy is passed from one wave-particle to its immediate next particle in the medium. This wave is the outcome of the continuous periodic movement of the particles. The distance covered by the propagation of a wave is determined by the transmission medium. There is little translational motion involved in this type of propagation. The oscillating material performs motion at a stationary point. In this case, the transfer of energy happens through a medium. This type of wave is a result of the oscillation of matter. The mechanical waves are seen as a propagation of a specific disturbance that travels in a material medium. In this way, waves help in communication between people. Later, these electric signal travels either wirelessly or via copper wires to the receiver through an antennae. Your phone converts the received voice signal into an electrical signal. The communication from the sender to the receiver appears in the form of a waveform. When you call your friend then the entire communication on the phone happens through the transmission of waves. Some of the types of waves are radio waves, sound waves etc.Īn individual is completely dependent on a wide range of waves for wireless communications. ![]() They are present around us in both visible and invisible forms. It appears in the form of oscillations when they pass through any medium (in case of water waves or sound waves) or without any medium (in case of electromagnetic waves). Waves refer to the transfer or flow of energy from one point to another without the transfer of matter. ![]()
