If an object is placed at a distance of 8 cm from a concave mirror of focal length 10 cm, discuss the nature of the image formed by drawing the ray diagram.
Here, the focal length $(f)$ of the mirror is given 10 cm, and the object is placed at a distance of 8 cm. This means that the object lies between the pole $(P)$ and the focus $(F)$ of the concave mirror. Thus, the image formed is virtual, erect and magnified.
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.
