Law of reflection & the periscope
Activity write up
Part 1
- Objective: prove that the law of reflection holds for a plane mirror.
- Construct the image
of the pin as described in the handout.
- Build a data table that
shows the angle of reflection and incidence.
Part 2
- Apply the law of reflection
to the sketch of the periscope and object arrow. You should show the angle
of reflection, normal and the angle of incidence.
- Draw a ray path from both the tip of the arrow and the base, this will
give you a clear picture of the arrows orientation at the eye piece.
