Trace you actual setup on your graph paper. Label all parts of the diagram.
Now, aim the Pasco triple beam at a concave reflective surface?
Trace your setup on the graph paper. Label all parts of your diagram.
Did you label the incoming ray, reflective surface, outgoing ray?
Using your protractor and your diagram, measure the angle between the incoming ray and the reflective ray?
Experiment placing the focal point of the reflection to the left, right and center or the incoming rays!
ON YOUR OWN: Repeat these procedures, except this time use the convex reflective surface. Trace and draw your results on graph paper. Compare and contrast the differences (if any) between the concave and convex reflective surfaces.
