155 Finding the angle of the prism ( α ) : With the slit width narrowed down sufficiently and prism table leveled, lock the prism table and note the angular position of the telescope when one of the reflected images coincides with the crosswires. Repeat this for the reflected image on the otherside (without disturbing the prism and prism table). The difference in these two angular positions gives 2 α . Finding angle of minimum deviation ( δ m ): Unlock the prism table for the measurement of the angle of minimum deviation ( δ m ). Locate the image of the slit after refraction through the prism as shown in Fig. 3. Keeping the image always in the field of view, rotate the prism table till the position where the deviation of the image of the slit is smallest. At this position, the image will go backward, even when you keep rotating the prism table in the same direction. Lock both the telescope and the prism table and to use the fine adjustment screw for finer settings. Note
