Question

When a rectangular glass block is placed in a liquid of of uniform density array of light follow the path as so study the diagram carefully and answer the following question a does the speed of light increase or decrease as inter glass. B-when the re emerge from the class block how much is it's angular deviation with respect to the incident ray . C- if a Ray of light where to be incident normally on the first surface of the glass block what would be its path through the block and the liquid draw a ray diagram for this Ray. D- if it is desired that are of light of one colour may not suffer any refraction at at the boundaries of the glass block what should be the ratio of the speed of light through the the liquid of its speed throw glass
