Description: How and why light changes direction or is refracted when it passes from one substance into another is graphically illustrated in this film by laboratory demonstration and animation., Uses laboratory equipment to explain and demonstrate the principles of refraction. Covers the angles of incidence and the velocity of light in different media. Demonstrates the index of refraction and uses geometric diagrams to explain Snell's Law. Uses prisms and lenses to further illustrate the principle of refraction and explain critical angle.

Complete Record: How and why light changes direction or is refracted when it passes from one substance into another is graphically illustrated in this film by laboratory demonstration and animation., Explains the operation of the principles of refraction and gives examples. Then demonstrates critical angle and internal reflection, and shows applications of prisms in the submarine periscope and prismatic binoculars., NOTE: Two (or more) records have been merged together to create this data.
