Refraction of Light
Don't shine like a diamond, refract light like a diamond. Young scientists use an acrylic block and a laser light to observe refraction. Advanced scholars figure the sine of the angles of reflection and incidence as well as mastering...

Reflection and Refraction
What is a prism? A place for light waves that commit minor refractions! The thorough resource includes three hands-on investigations covering light reflection and refraction; mirrors, lenses, and images; and optical systems. Subject...
