Question

A real, enlarged and inverted image can be obtained by using a concave mirror
A. True, when the object is placed between F and C
B. True, when the object is placed between 2F and C
C. False, when the object is placed between F and C
D. True, when the object is placed at C.

Answer 1

Hint: When an object is kept between the centre of curvature and focus, a real, enlarged and inverted image is formed. One ray passes through the focal point and reflects parallel to the optical axis. Another ray is first parallel to the optical axis, then reflects through the focal point. An image is formed at the point where the two rays converge.

Complete answer:
If we place an object AB between the centre of curvature and the focus, an image A’B’ will be formed. One ray will be parallel to the principal axis and after reflection through the concave mirror will pass through the focus. Another ray will initially pass through the focus, but after reflection through the concave mirror, will become parallel to the principal axis. Somewhere beyond the centre of curvature, the two rays will converge. At that point, an inverted and enlarged image will be formed. Also, this image is real as it is formed due to the actual convergence of reflected light rays at the location of the image. Moreover, real images are formed on the same side of the mirror as the object.

Hence, the correct option is (A).

Note:
Concave mirrors are the only mirrors that magnify images. An image larger than the object and also upright can be formed if the object was placed within the focal length of the mirror. However, this image would have been virtual.
