Question:medium

If the angle of minimum deviation produced by an equilateral prism is equal to the angle of the prism, then the refractive index of the material of the prism is nearly

Show Hint

The condition for minimum deviation is a special case where the angle of incidence equals the angle of emergence, and the light ray passes symmetrically through the prism. The prism formula is derived directly from applying Snell's law at both faces under this symmetric condition.
