Answer 2

Draw a normal M1N1 at O2. Join O1 and O2. It will represent the path of ray inside the glass slab, i.e. refracted ray. Repeat the experiment by taking the different angles of incidence such as 45° and 60° on the other part of paper and measure the angle of refraction and emergence accordingly and tabulate them.
