Which is the reflected ray?

A spherical surface of radius of curvature R, separates a rarer and a denser medium as shown in the figure. Complete the path of the incident ray of light, showing the formation of a real image.

In the figure given below, PQ represents an incident ray falling in the side AB of a prism, when monochromatic light is used .Draw the incident ray and refracted ray, at the angle of minimum deviation

Light of wavelength 5000 Å falls on a reflecting surface. For what angle of incidence is the reflected ray normal to the incident ray?
