- Place a sheet of paper on the table in front of
the mirror then use the ruler to trace the pathway of the beam to and from the mirror. - Label the incidence beam and the reflective beam.
- Using a protractor, measure these angles in
degrees. Record your results in thetable below. | |
Trial | Angle of incidence θi | Angle of Reflection , θr |

Draw the normal and reflected rays knowing the
Law of Reflection (qi=qr) . Write the values of the angle ofincidence and angle of reflection in the table above.
How do the angle ofincidence and the angle ofreflection compare for each trial?
