Question

Explain the images formed by a concave mirror.

Answer 1

The image formed by a concave mirror is both real and virtual .

When the object is placed very close to the concave mirror , it forms a virtual image .

And if the distance between the  object and the mirror  increases , the size of the  image decreases , which forms real images .

Answer 2

There is a formation of different images in a concave mirror. It mainly depends on the distance between the object and the mirror. Concave mirrors form both real and virtual images. When the concave mirror is placed very close to the object, a virtual and magnified image is obtained and if we increase the distance between the object and the mirror, the size of the image reduces and real images are formed. These real images can be projected on a screen. The focal point and the centre of curvature of the concave mirror lie in front of the mirror.
