a) Multiple images are the images that are formed when two or more mirrors are placed infront of each other and an object is placed between them.

b)Lateral inversion - The phenomenon of left side appearing right side and. right side appearing left side on reflection in a plane mirror is called. lateral inversion.

c)Dispersion of Light' can be defined as the splitting of white light when it passes through a glass prism into its constituent spectrum of colors (i.e. violet, indigo, blue, green, yellow, orange and red). Dispersion figuratively means 'distribution'.

d) The angle at which any light ray fall on point.
