Answer 2

An optical device produces a magnification of -1. The device may be known as a concave mirror.

• Concave mirrors can produce images of magnification -1, while convex mirrors always produce diminished images, so their magnification is always less than 1, and plane mirrors always produce images of the same size, so their magnification is always greater than 1.
• The magnification of a magnifying glass is determined by the distance between the user's eye and the thing being viewed, as well as the total distance between the user's eye and the object being observed.
• The ratio between the sizes of the pictures created on the user's retina with and without the magnifying glass is known as magnifying power. When the lens isn't being used, the user will normally get the item as near to the eye as feasible without it becoming fuzzy.
