Question

explain me what is waves

Answer 1

n physics, a wave is an oscillation accompanied by a transfer of energy. Frequency refers to the addition of time.

Answer 2

here is ur answr

In physics, a wave is an oscillation accompanied by a transfer of energy. Frequency refers to the addition of time. Wave motion transfers energy from one point to another, which displace particles of the transmission medium–that is, with little or no associated mass transport. Waves consist, instead, of oscillations or vibrations (of a physical quantity), around almost fixed locations.                                                                                                 A wave is a disturbance that transfers energy through matter or space.
