What is sound wave?
This is what we call energy that travels in waves and can be heard.
What is sound?
The _____________ makes the vibrations fast or slow
What is pitch?
This picture shows what a _______ pitch.

What is a high pitch.
You hear thunder after lightning because sound travels this compared to light (faster or slower).
What is slower?
