Detailed Solution

Concept- The mirror coating is located inside the sphere-shaped surface of a convex mirror. The convex mirror creates a smaller, upright, and virtual representation of the thing. In contrast to the concave mirror, where the mirror coating is outside the spherical surface, the image will be closer to the mirror than the object. When the other vehicles are very far away, the image of the back field of view should be virtual, focused, and very small in size, and the mirror may generate a clear, distinct image. You may create this kind of image by utilising a convex mirror. Therefore, using a convex mirror as the rear-view mirror is ideal. Hospital flats, subways, and traffic mirrors are additional locations where convex mirrors are used. Because they provide a magnified image of the object, concave mirrors are utilised in telescopes, medical equipment, shaving mirrors, and other devices.
