Hands-on Experimentation and Practical Investigation
Experiment 1: Reflection
Students investigate the law of reflection using mirrors and a light source.
Materials
- Plane mirror
- Laser pointer or flashlight
- Protractor
- Paper and pencil
Procedure
Students direct a light beam toward the mirror and measure the angles of incidence and reflection using a protractor.
Observation
Students verify that the angle of incidence equals the angle of reflection.
