Sound and Light

Sound and Light

Sound can travel differently through different objects. For example, sound travels slow in solids, medium speed in liquids, and really fast through gases. to understand more, picture yourself in a big crowd of people, like in a concert. It will be hard to get to the front because everybody is crammed together. This represents sound going through a solid. Now picture yourself at the mall. Its busy there, but you can get by faster. this represents sound going through a liquid. Now picture yourself at your house. it is most likely to get through easier because there is not many people at your house. This represents sound going through a gas. Since gases are really spread out, sound can travel the fastest through them. Sound occurs when an object vibrates. Examples of light would be a bonfire, and a streetlamp. Both sound and light can travel in waves. There are two types of waves. They are longitudinal waves and transverse waves. The wave that is used for sound is the longitudinal wave. Light can refract. Such as when you put a pencil In water and you look at it from the side, it will look as if the pencil has broken in half. Interestingly, since space is just a big open empty place, there is no sound heard! The Cochlea is a part of your ear that helps you hear. How it works to help you hear is when the tiny hairs move from your ear, they convert the vibrations into sounds. If you think about it, sound and light is all around us!
