Light is both a wave and a particle.
The wave nature was confirmed in the 19th century, and the particle nature was confirmed in the 20th century. Some of the confirming experiments can be done in a home laboratory. Students will be guided through experiments to demonstrate the behavior of waves and of particles, and to compare the behavior of light to each. The experiments will use a laser pointer, electrical tape, a superball, a mailing tube, a ball bearing, a bathtub, a frying pan, and a camera flashlamp. Additional experiments will be described on line.
