When do you notice light bending?

Light refracts or bends when it leaves one medium and enters another one (i.e. when it goes from air to water; when it goes from glass to air). This is because the speed of light is different in different materials (light travels in a vacuum at a speed of 3 x 10^8 m/s and is slower in all other mediums). When light slows down (i.e. moves from air into water), the light bends towards the normal; when light speeds up (i.e. moves from water into air), the light bends away from the normal.

light is never bent when travelling between media, only refracted. there is research into the bending of light around large objects in space and utilising the bending of electromagnetic waves to create invisible objects.

Light cannot bend. It only refracts. Refraction can happen through a change in medium. Such as a glass block. The light will slow down, or speed up, therefore changing direction.

This phenomenon is called diffraction. when light is incident on the opaque substances having width comparable to wavelength of light then light bend.
