What Are Waves?
Grade 4 · Science · Waves and Information · Alabama, USA
Lesson Summary
A wave is a disturbance that moves energy from one place to another. Waves are all around us in the form of sound, light, and water.
Explanation
Waves transfer energy without moving matter from place to place. Think of a wave at a sports event: people stand and sit, but nobody walks anywhere. Ocean waves work similarly; the water moves up and down, but it is the energy that travels forward. There are two main types of waves: transverse waves, where the movement is up and down (like ocean waves), and longitudinal waves, where the movement is back and forth (like sound waves).
