Light Ray Viewing Kit

The Light Ray Viewing Kit is a small "liquid laboratory." When used with any of our lasers it creates underwater light ray patterns and diagrams that constitute the basics of all introductory optic studies. In a complementary series of activities in the accompanying instruction guide, students can observe, and more readily understand, principles and equations such as:

• Snell's Law
• Total internal reflection
• Equal angles of incidence and reflection
• Critical angle of light

Set-up for each experiment requires less than five minutes and costs only a few pennies. ("Just add water!")
