point of incidence ← mirror Step 4 - 6 Create an Incident ray (between 0º and 90º), then measure the angle of reflection. point of incidence Repeat Step 4 - 6 for a different angle point of incidence Repeat Step 4 - 6 for a different angle Data Table Incident Angle 0º Reflected Angle Analysis What was your hypothesis? Was your hypothesis correct? Explain. 90º What is the angle of the reflected ray when the incident ray is on the normal line (0º)? Why is there no reflected ray when the incident ray is parallel to the surface of the mirror (90º)? The first law of reflection gives the relationship between the angle of incidence and the angle of reflection. Based on your data table, what is the first law of reflection? The second law of reflection states that the incident ray, the reflected ray and the normal line all lie in the same plane (flat surface). What flat surface was used in this investigation to demonstrate the second law of reflection?
