Question

repeat for four different and angle of incidence is equal to 40°,50°60° and 70°​

Answer 1

Answer:

For a triangular prism, trace the course of rays passing through it, measure angles i1, i2, A and

8. Repeat for four different angles of incidence (say i=40° , 50°, 60° and 70°). Verify i+

i2=A+S and A =ri +r2.

Answer 2

Angle of incident i= Angle of emergence = 3/4 A

Where , A= Angle of prism

Since prism is equilateral A=60

∴i=e=60°×3/4=45°

From prism formula:

Angle of deviation , δ=i+e−A=45+45−60=30°
