The actions and effects of lenses: As light encounters a lens, the lens changes the direction of the rays. It can also be thought of as changing the curvature of the wave.
As the glass lens rotates two optical effects are observed: reflection and refraction. A straight object enters a liquid and appears to bend due to refraction as predicted by Snell's law. (320X240) (640 X 480) The changing in the curvature of the lens results in magnification of the image. (320X240) (640 X 480) The changing in the curvature of the lens results in decreased magnification of the image (320X240) (640 X 480) Characteristics of Light | Illustration of light as a ray | Illustrating Huygen's Principle | Diffraction | Holography | Eyes | Simple optical systems
