Investigating Reflection

Today, we have been investigating the angle at which light is reflected off a mirror.

Working together in a group, we shone a torch through a card with a slit in so that we got a thin beam of light. This shone onto the mirror and reflected back off.  We drew the light beam and reflected beam onto our paper, and carefully and accurately measured the angle of each with a protractor.

We found that the angle of incidence and the angle of reflection were equal.
