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.
