To produce an enlarged and erect image with a concave mirror,the object must be positioned
Answer Details
To produce an enlarged and erect image with a concave mirror, the object must be positioned between the principal focus and the pole of the mirror.
A concave mirror is a curved mirror that has a reflecting surface that curves inward like a spoon. It is also called a converging mirror because it converges the parallel incident rays of light to a single point known as the focus.
When an object is placed in front of a concave mirror, the light rays coming from the object reflect off the mirror and converge to form an image. Depending on the position of the object relative to the mirror, the image can be real or virtual, erect or inverted, and magnified or reduced.
If the object is placed at the principal focus of the mirror, the reflected rays of light will be parallel to each other, and the image will be formed at infinity. This image is real, inverted, and highly diminished.
If the object is placed beyond the center of curvature, the image formed will be real, inverted, and diminished.
If the object is placed between the principal focus and the center of curvature, the image formed will be real, inverted, and magnified.
Finally, if the object is placed between the principal focus and the pole of the mirror, the image formed will be virtual, erect, and magnified.
Thus, to produce an enlarged and erect image with a concave mirror, the object must be positioned between the principal focus and the pole of the mirror. Therefore, the answer to the given question is option (D) between the principal focus and the pole.
