Question

What is a wave?
A stationary object.
A disturbance that transfers energy through a medium.
A type of particle.

Answer 1

A wave is best described as **a disturbance that transfers energy through a medium**. Waves can occur in various forms, such as mechanical waves (which require a medium, like sound or water waves) and electromagnetic waves (which can travel through a vacuum, like light). They involve the transfer of energy without the permanent displacement of the particles of the medium.
