When light passes from one medium to another medium of a different density it bends. Refraction is the bending of light as it passes from one transparent medium into another. This bending by refraction allows us to make use of lenses, magnifying glasses prisms, etc. It also makes it possible for us to see because our eyes use lenses to focus images onto our retina. By using light microscopy, I aim to get refractions with the aid of different mediums.
