The Physics of Refraction and its Properties

Light is something that not many people thing about: we notice it every day, not really thinking about it. For us, light is vital, as it helps us see and is critical in the process of growing food, which we need. One of the properties of light is that when it goes through a transparent object, it gets refracted. This means that when the light goes goes from a medium of specific density to another medium of a different density, it's velocity changes along with its magnitude. This property is is useful because this varying degree of refraction can be used to calculate the density of objects.
