What are called waves? Mention their importance.

(N/A) wave is a disturbance that travels through a medium or vacuum,transferring energy from one point to another without the net transport of matter.
Definition: The patterns that move without the actual physical transfer or flow of matter as a whole are called waves. In general,the motion of a disturbance in a medium or vacuum is called a wave.
Importance:
$1$. Energy Transfer: Waves are the primary mechanism for transferring energy from one location to another without moving the medium itself.
$2$. Information Transfer: Waves allow for the transmission of information. For example,sound waves carry speech,and electromagnetic waves carry data in telecommunications.
$3$. Communication Systems: Modern long-distance communication (telephone,radio,internet,satellite) relies entirely on the transmission,propagation,and reception of signals in the form of waves.
$4$. Sensing and Detection: Waves are used in various detectors (like ears for sound or antennas for electromagnetic waves) to receive and interpret signals,enabling interaction with our environment.
