How Does Sound Work

Sound travels in waves and the faster the waves the higher the frequency. You cannot see sound waves. But you can picture what they look like. Sound waves look a bit like waves in water. What happens when you throw a stone into a pond? Waves go out in circles from where it hit the water. Sound waves also go out in circles too. They can go out of a drum, a guitar or even a car. They go out from whatever is vibrating.
