(i) Keep a glass slab on a blank paper and draw its outline PQRS as shown in the figure.
(ii) Draw an inclined straight line on the side of PQ so that it intersect PQ at N. Pierce two pins vertically at two points A and B along the line.
(iii) Look at the pins A and B from the opposite side of the slab and pierce pins C and D vertically so that the images of A and B are in line with C and D.
(iv) Now remove the chip and the pins and draw a straight line going through points C and D so that it intersects SR at M.
(v) Join points M and N. Observe the incident ray AN and emergent ray MD.
Questions:
(a) What is your observation about the emergent ray and incident ray ?
