When an object is kept within the focus of a concave mirror, an enlarged image is formed behind the mirror. This image is:
(a) real (b) inverted (c) virtual and inverted (d) virtual and erect
(d) virtual and erect
Explanation
A concave mirror is a mirror that is curved inward in the middle. It is also known as converging mirrors, due to the fact that when parallel incident rays fall on the surface of the mirror, the rays will reflect and meet at a particular point and form the image.
Depending on the position of the object with respect to the mirror, the types of images it forms are real, inverted as well as virtual and erect image, also the size of the images formed are magnified, diminished as well as the same size as that of the object.
When an object is kept within the focus of a concave mirror, i.e., between the focus, $F$ and the pole, $P$ of the mirror, a virtual, erect, and enlarged image is formed behind the mirror
