Science - sound

I have been learning things about sound.

Sound is a form of energy and travels through the air as waves.

Did you know the higher the pitch the sound waves are closer and the lower the pitch the further the waves are apart?

 Sound waves need air to travel. Sound waves travel at 340m per second.

The reason we hear is we have a drum in our ear and the waves hit the drum.
