1. Figure shows the refraction of a ray through a prism
Copy the diagram and ignoring dispersion at the faces
AB and AC mark the following angles :(1) The angle
of incidence. (2)The angle of refraction at the face
AB. (3) The angle of emergence. (4) The angle
deviation​

Answer 1

Explanation:

BC,=incident ray, DE=emergent ray, A=angle of prism, I =angle of incidence,e=angle of emergence

Answer 2

Answer:

1,2 are correct

Explanation:

when light incident on surface of prism it travels through medium then it get refracted away from the normal by producing Vibgyor
