Question

calculated the r.i the material of an equilateral prism if the refracted ray is parallel to the base of the prism and the incident ray is deviated through 30°.​

Answer 1

Answer:

n = √2

Explanation:

as the prism is equilateral the angle of prism = 60°

now the deviation = 30°

R.I of the prism = sin(60+30/2)/sin(60/2)

=sin45°/sin30° = 2/√2 =√2
