A wave is a disturbance that moves through matter(物质). Energy creates the disturbance that makes a wave. Ocean waves are created when energy disturbs the water. Most water waves are caused by wind blowing across the water's surface.Tsunami waves are not like most water waves, however. ...

What is a surface acoustic wave? What is a retrograde P wave? What is the T wave in an ECG? What are septal Q waves? What do analog waves look like? What is anemometer? What is diffraction? What type of wave is ultrasound?
Time period: The time period of a square wave is one of the key parameters that describes the waveform. As the main features of the square wave are the rising and falling edges, these are the key areas that are used for the markers for defining the time period. Eit...

A mechanical wave is transverse when all the particles of the medium, which are solid or liquid (and never gas), vibrate perpendicularly at right angles, up and down, and continue to move in the direction of the wave. For example, the ripples on the surface of a lake are transverse wav...
The phase velocity is given as: where λcis the wavelength of light. 4. Wavelength:In a waveguide the effective wavelength of an electromagnetic wave differs from its free-space wavelength due to the constraints imposed by the geometry of waveguide. This difference is explained by the phase velo...
