The light ray Incident at one face of the prism is shown in figure. Copy this figure complete the path of the ray. (Take critical angle of prism C = 42 degree)

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.

A ray of light parallel to the principal axis of a spheri cal mirror falls at a point M as shown in the figure,Complete the ray diagram and mark the angle of incidence and angle of reflection

Green light is incident at the Polarizing angle on a certain glass plate as shown in figure.Indicate the polarization components on the reflected and refracted rays, by arrows and dots.
