Doppler Effect at Mach 1

We all have seen waves at the beach, but how is it that sound and light also move in waves?

How can we produce waves? In what ways can we describe them?

The lessons in this unit are geared to students in elementary, middle school and high school. Students will learn about the key properties of waves and how they work in our world.
