Light Ray Viewing Project w laser .5 mW / Class II
Project for easy viewing of light rays

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!")

Project equipment includes: impact-resistant observation tank, four ounces of scattering solution, first-surface mirror, stirring rod, ruler, protractor, full-color instruction guide and .5 mW Class II helium neon laser.
