Reflection of Light. Use your information from class to complete the sheet on light. 1. Label the diagram to include: i) Angle of incidence ii) Angle of reflection iii) Direction of light iv) Lamp v) The normal. 2. Measure the angle of incidence and the angle of reflection with a protractor. Write this on your diagram. 3. Based on your light experiments in class, draw an accurate, scale diagram (that means use a ruler and protractor!!) of a periscope and show all the angles and rays of light. You will use this lesson.
