Sign in to track this film in your collection or want list.
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.
