Activity 11.1
Fix a sheet of white paper on a drawing board using drawing pins.
Place a glass prism on it in such a way that it rests on its triangular
Draw a straight line PE inclined to one of the refracting surfaces,
base. Trace the outline of the prism using a pencil.
say AB, of the prism.
Fix two pins, say at points P and 9. on the line PE as shown in
Fig. 11.4.
Look for the images of the pins, fixed at P and 9. through the
other face AC.
Fix two more pins, at points R and S, such that the pins at Rand
S and the images of the pins at P and 9 lie on the same straight
line.
Remove the pins and the glass prism.
The line PE meets the boundary of the prism at point E
(see Fig. 11.4). Similarly, join and produce the points R and S. Let
these lines meet the boundary of the prism at E and F, respectively,
Join E and F.
Draw perpendiculars to the refracting surfaces AB and AC of the
prism at points E and F. respectively.
Mark the angle of incidence (Zi). the angle of refraction (Zr) and
the angle of emergence (Ze) as shown in Fig. 11.4.
