Question

when an object was kept at position x in front of a concave mirror, an enlarged and virtual image was formed. which among the following identifies 'x' correctly? (a) anywhere between the centre of curvature and principal focus (b) anywhere between the pole and principal focus (c) exactly at the centre of curvature (d) exactly at the principal focus

Answer 1

The correct position 'x' for an object to produce an enlarged and virtual image in front of a concave mirror is anywhere between the pole and the principal focus of the mirror.

Step-by-step explanation:

When an object is placed in front of a concave mirror and an enlarged and virtual image is formed, this indicates that the object is positioned between the principal focus (F) and the mirror itself. This specific placement means that the object is located somewhere between the pole of the mirror (P) and its principal focus.

In this situation, the rays diverge after reflecting off the mirror, and when extended backwards, they seem to originate from a point behind the mirror, hence creating a virtual image that is enlarged and upright.
