This site from Georgia State University is an indexing page for several other pages on the topic of reflection. Topics are treated in an understandable manner and utilize meaningful graphics.
Science Education Resource Center at Carleton College
Serc: Virtual Photoelectric Lab
In this activity, students measure the relationship between kinetic energy of photoelectrons and the frequency of the incident light.
