The incident ray is refracted towards the normal as it enters the glass prism from air. It is then refracted away from the normal at the boundary between glass and air as it leaves the prism.

In our setup a beam is reflected by an air–glass interface and its transverse ... team have a Letter on angular deviations of a light beam upon reflection on page 337 of this issue.

When light travels from air into glass it slows down because glass is more (optically) dense than air. This change in speed can cause the light to bend at the boundary between the two transparent ...

But sometimes reflections can be annoying. They can get in the way of what you want to make pictures of. This usually happens with windows, where light bouncing off the glass can obscure your subject.

There are numerous glass cleaning solutions available in ... by a fracture or flaw in a windshield can also lead to uneven ...

Ray explains the origins of light, its crucial role in visibility, and how it interacts with various surfaces through reflection and refraction. The film covers topics such as the speed of light ...
