Refraction of Light in Glass Block

Leave a comment

Refraction is the bending of light as light travels from one medium to another medium of different refractive index.


As light travels from less dense medium (air) to the denser medium (glass), it bends towards the normal as the speed of light decreases in the medium.


The video below show how the refraction takes place in the glass block and how to position the needles in line.
