Question

In concave mirror, the size of image depends upon

Answer 1

Answer:

The distance of the object placed on the principal axis from the concave mirror.

Explanation:

In a concave mirror, the nature of the image formed formed by the object placed in front of the mirror depends on the position of the object placed in from of the mirror. It all depends on the distance between the mirror and the object placed on the principal axis.

The closer the object is to the lens, the more larger or magnified the image formed will be. For example an object placed between the focal point and the pole of a concave produces a much larger image than an object placed beyond the centre of curvature of such mirror.

Answer 2

Answer:

The location of the object relative to the vertex, V, the focus, F center of curvature, C and infinity

Explanation:

The location of the object relative to the vertex, V, the focus, F center of curvature, C and infinity such that;

The image of an object placed at V, touching the mirror is the upright and the same size as the object and virtual

The image of an object placed between V and F is upright and magnified also virtual

The image of an object placed at the focus is at infinity

The image of an object placed between C and F is real, magnified and inverted

The image of an object placed at C is real, same size and inverted

The image of an object placed between C and infinity is real, diminished and inverted

The image of an object placed at infinity is size zero and real.
