About the Diagram

Introducing the diagram! Read back and forward between the image at the top of the page and the explanation below!

Overview

Everything we see in the world is a product of reflection. As light travels through the air it is invisible, but when light that has been reflected off the surface of an object enters our eyes it forms an image that light-sensitive cells react to. Let’s take a close look at the basics of reflection.

The diagram

This diagram shows sunlight being reflected off a fish in water and provides a close-up view of what is happening in another of our diagrams: Refraction, Reflection and Total Internal Reflection.

  • The source for the incident rays is sunlight. It this situation the Sun can be considered to transmit parallel rays of light.
  • If each scale on the fishes skin has an uneven surface and causes the rays to scatter as they are reflected this causes diffuse reflection.
  • Diffuse reflection takes place when light is scattered as it reflects off a rough surface. When reflected light scatters randomly it doesn’t produce a mirror-image.
  • Some kinds of fish scales can appear iridescent. Iridescence is the phenomenon produced by certain surfaces that appear to gradually change colour as the angle of view or the angle of illumination changes. Other examples of iridescence include soap bubbles, feathers, butterfly wings and seashells. Iridescence is often created by microstructures that interfere with the path of light rays.
