Solution
(a) Lateral Inversion. The phenomenon due to which the image of an object turns through an angle of 180° through verticle axis rather the horizontal axis, such that right side of image appears as left or vice-versa is called Lateral Inversion. During lateral inversion, the left side of object appears as the right side of the image and vice-versa. In a way, the image turns through the angle of 180° about a vertical axis.
