On Fig. 2.1, draw the normal NL at the centre of side AB. Continue the normal NL so that it passes through side CD of the block. (a) · Label the point F where the normal NL crosses side AB. Label the point G where the normal NL crosses side CD. On Fig. 2.1, draw a line EF at least 7 cm long above side AB and at an angle i = 30° to the left of the normal. Label the end of the line E. (b) · Mark the positions of two pins P, and P,, to act as objects, on line EF at a suitable distance apart for this type of ray-trace experiment. The student looks from the position of the eye shown in Fig. 2.1, to observe the images of P, and P, through side CD of the block. She adjusts her line of sight until the images of P, and P, appear one behind the other. (c) . She places two pins P, and P between her eye and the block so that Pa, P and the images of P, and P,, seen through the block, appear one behind the other. 1. 21 The positions of P, and P are marked on the ray-trace sheet. (i) Draw a line joining the positions of P, and P. Continue the line through the block until it extends to just outside the outline of the block.
