Sound

Sound is used to make people hear the vibrations that are happening around us.
- A vibration is when an object vibrates sending the vibration to our ears making us hear clearly.
Echoes is when the sound that you produced is reflected back from a hard surface that it comes back to you.
- Fishermen use this signal to also catch shoals of fish.
Sound is not as fast as light so in a lightning bolt first you see it than the sound is heard
- Sound Waves are waves that you can see on an ocilloscope which reads the sound wave.
Sound travels the fastest through solids not like light, it is the total opposite of light.
