KEY CONCEPTS:
1. What are waves, and how are waves produced?
longitudinal waves
a wave in which the disturbance is parallel to the

Let us learn some vocabulary

mechanical waves

a wave that can travel only through matter.

Let’s Begin

What are Waves?

electromagnetic waves Waves always begin with
a source of energy that
a transverse wave that can travel through empty causes a back-and-forth or
space and through matter. up-and-down disturbance,
or movement.

A wave is a
disturbance that
transfers energy
