Refraction Of Light:

Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows. Even our eyes depend upon this bending of light.


The change in direction of the light when it goes one medium to another medium is called
a) reflection                         

b) transmission
c) absorption                       

d) refraction
