Explain how the formation of a rainbow occurs.
Draw a ray diagram to show the refraction of a monochromatic ray through a prism when it suffers minimum deviation
Draw the diagram given below and clearly show the path taken by the emergent ray.
A ray of light OP passes through a right angles prism as shown in the adjacent diagram.
(a) State the angles of incidence at the faces AC and BC.
(b) Name the phenomenon which the ray suffers at the face AC.
