Optical Effects

When light is reflected, refracted, scattered or diffracted, it creates incredible displays of colour and shape, whether it’s a rainbow or crepuscular rays.

Light can be reflected (from a mirror or water’s surface), refracted (as it passes through a raindrop), scattered (by particles of dust in the air) or diffracted (like a corona around the Moon) either individually or by a combination of the above. When it does so, we can see some breath-taking and rare phenomena. Here are some examples.
