Identify the characteristics of electromagnetic and mechanical waves. . What are waves?. Waves carry energy. Rhythmic disturbances that carry energy without carrying matter are called waves.. SOUND IS…. (for our purposes). Movement of the air that happens at human hearing frequencies:. 20 - 20,000 cycles per second. The easiest case to imagine is a “monopole” sound source.. Imagine a ball suspended in the air that expands and contracts, pushing and pulling on the air around it.. What is a wave?. A wave is a repeating disturbance or movement that transfers energy through matter or space. Waves transfer energy not matter. The water waves below are carrying energy but are not moving. Waves can only exist as they have energy to carry.. Almost all of our information on the heavens is derived from the light we see. We have returned samples from the Moon and a comet . Also obtained meteor samples. We have landed (with unmanned probes) on only a handful of planets and moons. Frequency. Medium. Vibration. Sound Waves. Compression . Rarefaction.
