Question

What type of mirror is used whenever a magnified image of an object is needed ?

Answer 1

Hint: Magnified image is the method of enlarging something as an optical image or the ratio of image size to object size. A magnified image is one that has been magnified by a mirror or lens. Magnification is the size of an image in relation to the size of the object that produced it in optics.

Complete answer:
A convex mirror employs a convex lens to visually enlarge objects. They frequently have a maximum magnification of five times. Since their convex lenses (convex means bent outward) refract or bend light rays so that they converge or fall together, convex mirrors make objects appear larger. A convex mirror can magnify an image in conditions that aren't present in the standard setup.

A convex mirror can only produce a simulated upright image of reduced size when a real object is present. A real magnified image can be formed by reversing the rays, where a virtual object (rays that would converge into a real image) replaces a virtual image. A secondary convex mirror magnifies the image of the main concave mirror in a Cassegrain Reflector in the same way.

Henec, we can say that a convex type of mirror is used whenever a magnified image of an object is needed.

Note: Firstly we considered that a convex lens is included inside a convex mirror. We already knew that Magnifying glasses are frequently made with convex mirrors. As we found that convex lenses refract rays so that they converge, we made sure that convex mirrors make objects appear larger. All of us know that Binoculars, cameras, microscopes, and telescopes all have magnifying lenses (convex lenses) as part of their construction and thus we can justify our answer.
