(i) The glass slab should be perfectly rectangular with all its faces smooth. 

(ii) While fixing the pins P1 and P2 or the pins P3 and P4 care should be taken to maintain a distance of about 5 cm between the two pins. This would help in tracing the direction of the incident ray and that of the emergent ray with Greater accuracy.
