Light is very interesting in terms of photography. Light can be manipulated in many ways, wether that be natural sunlight, or even studio lights, we have to have an element of it in every photo, otherwise there would be no photograph.
With this study, I decided to have a look at light itself, which can be hard to do.
However, if you stand in a dark room, turn your shutter speed / exposure to the correct requirement, then your camera can actually capture light as it moves. Now, it can't capture natural light, but something such as a glow stick or a phone light, the camera will be able to capture the path that light takes.
