Waves
Mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium.
Electromagnetic Waves are waves that are created as a result of vibrations between an electric field and a magnetic field.
There are three types of mechanical waves: Transverse wave, Longitudinal wave, and Surface waves.
Transverse wave is a wave vibrating at right angles to the direction of its propagation.
Longitudinal wave is a wave vibrating in the direction of propagation.
Surface wave is a mechanical wave that propagates along the interface between differing media.
Electromagnetic waves are waves that have no medium to travel whereas mechanical waves need a medium for its transmission. Electromagnetic waves travel in a vacuum whereas mechanical waves do not. ... While an electromagnetic wave is called just a disturbance, a mechanical wave is considered a periodic disturbance.
Amplitude is the maximum displacement of the medium from it's rest position.
Period is the time required for one cycle
Frequency is the number of complete cycles in a given time.
Wavelength the distance between successive crests of a wave especially points in a sound wave or electromagnetic wave.
Wave speed is the speed at which a wave travels.
