Reflection

All waves are reflected when they hit a surface or barrier.  The angle at which the wave is reflected is not random, but predictable.  We will investigate angles of incidence (i) and angles of reflection (r) of light waves hitting a plane mirror and try to answer these questions about light and reflection:-

  • Light travels in straight lines.  What evidence can you think of that shows this?
  • What is a virtual image?
  • What does laterally inverted mean?

This link gives some basic information to start with.  This one gives a bit more detail.
