The diagram shows the path of a ray of light through a rectangular glass block placed in a liquid of uniform density.
What is the angular, deviation of the emergent ray from the glass block with respect to the incident ray?

उत्तर
As shown by the line in the diagram, the emergent ray is parallel to the incident ray (when produced) and so there is no angular deviation.
