Question

(i) A concave mirror produces a magnification of -1. The object is placed:
(a) at the focus (b) between focus and centre of curvature
(c) between focus and pole (d) at the centre of curvature

Answer 1

Explanation:

I think (c) is correct answer

I am not sure

but pls mark as brainlist

Answer 2

Answer:

Concept:

A hollow spherical can be made into a mirror by cutting it into pieces, painting the exterior surface, and using the interior surface as the reflecting surface. Concave mirrors are this kind of mirror.

Explanation:

In a concave mirror, magnification is detrimental. The height of the image divided by the object's height determines the concave mirror's magnification. As a result, the magnification will be negative if the image is actual but inverted.

Magnification m = -1

The focal length is negative.

we have the formula for magnification that is -v/u

                         -v/u = -1

                            v = u

So the concave mirror produces a magnification of -1. The object is placed at the center of curvature.
