Question

to study the phenomenon of refraction through prism by pin method and hence to determine the angle of deviation​

Answer 1

Explanation:

To measure the angle of deviation.

Draw a normal N2GN3 to the refracting surface AC at point G. Mark the angle of incidence (∠i), angle of refraction (∠r) and angle of emergence (∠e) as shown. Now, produce EF to M and GH to O which will meet at point J. Measure ∠GJM as the angle of deviation ∠δ.
