Question

what is a wave? explain me plz

Answer 1

In physics, a wave is a disturbance that transfers energy through matter or space, with little or no associated mass transport. Waves consist of oscillations or vibrations of a physical medium or a field, around relatively fixed locations. 



hope it will help you

Answer 2

A wave is a kind of oscillation (disturbance) that travels through space and matter. Wave motions transfer energy from one place to another. Consider this example the

first thought concerning waves invokes up a picture of a wave moving across the

surface of an ocean, lake, pond or other body of water. When a pebble is thrown

in a pond, it creates a disturbance and forms ripples which travel together as

a front in a straight-line direction, or the waves may be circular waves that

originate from the point where the disturbances occurs in the pond. The wave is

defined as the energy transferred through medium with regular vibration or

oscillating motion. A few examples of waves are:  water wave, light wave, electromagnetic wave,

sound wave, seismic wave (earthquakes). The waves are classified mainly two types that are longitudinal wave and transverse waves. The sound waves are good example of longitudinal wave which is travelled medium with the use of force. This force is exerted between molecules of the medium. The electromagnetic radiations are transverse waves which also include the light waves. These waves show displacement in the perpendicular direction of the field intensity vector. The quantum theory gives the description of wave properties which includes wave intensity, wave number, wave frequency, energy of wave, wavelength etc. the motion of wave and its full study is physical phenomena. Let’s discuss wave properties and some examples of waves.
