Lenses

Lenses. As light enters into a new medium it may bend due to refraction. So on a flat piece of glass all light rays remain parallel. Snells Law states that the ratio of the sin of the angle of incidence to the sin of the angle of refraction is a constant for each material. Lenses.

  2. As light enters into a new medium it may bend due to refraction. So on a flat piece of glass all light rays remain parallel Snells Law states that the ratio of the sin of the angle of incidence to the sin of the angle of refraction is a constant for each material.

  3. Lenses Lenses are transparent spherical materials, usually glass, that refract light waves.
