This experiment seeks to demonstrate the law of reflection - the angle of incidence is equal to the angle of reflection when measured from the normal. Equipment Single slit raybox with power supply Paper Ruler Protractor Sharp Pencil Plane mirror Support for mirror (e.g. wooden block with a groove in, or plasticine) Method Draw a line on the paper. Place the mirror on the line and support it so it does not move. Shine the beam from the raybox towards the mirror. Use the pencil

incidence compares with the angle of reflection by always sharing the exact same measurement. For each trial performed, the incident ray would be directed towards the mirror and the reflected ray would match the incidence ray but would reflect the other way. For example, when trial 1 was performed and the angle of incidence was aimed on the plane mirror, its angle equaled 45°. The angle reflected off the mirror in the same angle which also equaled 45°. This reflection came off a smooth surface which was
