उत्तर
The angle made by the incident ray with the normal to the first face of the prism is called incident angle, which is angle Y here.
The angle made by the emergent ray with the normal to the surface when it comes out from the prism after refraction is called emergent angle, which is angle Q here.
The angle between the incident ray and the emergent ray is called angle of deviation, which is angle P here.
Hence, the correct option is D.
