//Distortion//
This image illustrates the physics behind distortion. This image seen is the reflection of a cityscape in a glass building. The building's windows function as mirrors, which distort the cityscape image. This distortion is caused by the distortions in the glass of the windows. The windows' glass acts as many small lenses of varying shapes, which reflect the rays of light in different directions, resulting in a distorted image in the building's glass.
