why does light bend while striking any object

Asked by archanajnk 1st January 2015, 7:33 PM
Answered by Expert

When light travels from one medium to another, at the boundary of the two media, it bends.

This is because the speed of light changes according to the refractive index of the two media.

This causes the light to either slow down or speed up in the second medium and hence, bend towards or away from the normal respectively.
