Question

what does a emergent ray in a prism bend at an angle to the direction of the incident ray
​

Answer 1

Answer:

There u go

Explanation:

The angle at which the incident ray passes through the surface of the prism to the normal is called an incident angle and the angle by which the ray emerges out of the prism to the normal is called an emergent ray. ... When a ray of light enters from lighter medium to denser medium it bends towards the normal.

Answer 2

Answer:

Explanation:

When an incident ray of light enters a prism it gets refracted towards the normal. This refracted ray then strikes the other face of the prism and further deviates away from the normal and leaves the glass prism to enter the air i.e. from one medium to the other. This ray that leaves the prism is called emergent ray. Thus the emergent ray bends away from the normal.
