1. Make a sample problem and answer it. (Just like the example)2. What will be the angle of emergence if a ray is incident on a prism at an angle of 20 degrees if the apical angle of prism is 60 degrees and the index is 1.62?Example is posted below:

ANGLE OF EMERGENCE For r = law of refraction Apical Angle /- 50 sin i. n2 Smr i = 30 A B A = 90 - angle of refraction () C B = 180 - (A + Apical angle) C = 90 - B 65 .50 Emergence (e) sinc n2 Sin e nl
