Refraction of light
Refraction of light The change in direction of light when it passes from one medium to another obliquely is called refraction of light. In other words the bending of light when it goes from one medium to another obliquely is called refraction of light. The Refraction of light takes place when light rays enter from air into glass , or from glass into air. The refraction of light takes place when light enters from air into water, or from water into air. And the refraction of light also takes place when light enters from water into glass or from glass into water. The optical instruments like camera, microscope and telescope work on the the refraction of light through glass lenses. The refraction (or bending ) of light takes place at the boundary between the two media. Causes of refraction- The refraction of light is due to th...
