Arc lamp and mirror on large disk rotate showing beam angles.

6A10.11 • E+40+0

Arc lamp, with mirror on large rotateable disk showing beam angles. This apparatus is designed to show that the angle of incidence equals the angle of reflection. White light from a carbon arc shines through a slit, producing a ray that reflects off a front-surface mirror mounted on a large white rotateable disk marked with degrees. The ray also glances against the disk, making it visible to the class.
