Source 4: http://earlscience.blogspot.co.uk/2011/03/simple-experiment-law-of-reflectiono.html

You could also try using an internet search for things like:

"angle of reflection investigation"
or
"GCSE reflection investigation"

You can even use a textbook! Just make sure you write down the author, title and year of publication  if you do

The Hypothesis

You have been given this hypothesis:

"The angle of reflection depends on the angle of incidence"

You need to design an investigation to test this hypothesis, and therefore to help See-well mirrors check whether their mirrors work perfectly.

The Context

See-well Mirrors make rear view mirrors for a range of car companies. They have been getting complaints that a recent batch of mirrors are causing road accidents

They need you to come up with an experiment to prove that their mirrors are perfect, and that the accident was not their fault.
