A ray of light is incident at an angle 52° on the face of equilateral prism and gets through 34°.find the angle of emergence A ray of light is incident at an angle 52° on the face of equilateral prism and gets through 34°.find the angle of emergence
For an equilateral prism is -A = 60°Angle of emergence of the light ray is calculated by formula -i + e = A + d52 + e = 60 + 34Therefore, the angle of emergence of the ray is 42°.
