A beam passing through an object like a glass slab and water droplets is deflected twice: once entering, and again when exiting. The sum of these two deflections is called the deviation angle.

The light going through a certain deviation we can be sure that it has undergone a change of medium while moving in its path.
Explanation:
- If we imagine a certain line that is perpendicular to the point of meeting of the slab and the light ray then the raywood debate towards that line inside the slab this happens because the medium in which the light is entering is a denser medium.
- Then it was previously travelling in which means that the denser the medium gets the angle between the normal and the light ray would become much smaller and vice versa.
