What is a wave in physics? a. A stationary disturbance in matter b. A motion passing through matter without moving the matter C. A particle traveling through space d. An energy transfer without a medium

The correct answer is b. A wave in physics is a disturbance that travels through matter or space, transferring energy from one point to another without causing any permanent displacement of the medium through which it travels. Waves can be mechanical, such as sound waves, or electromagnetic, such as light waves, and they can travel through various media, including solids, liquids, and gases.
