Question

Image formation by concave mirror In this, when the object is focused, both the light rays are parallel, then how much is the image enlarged?
Explain....it.....​

Answer 1

Object is in between the principal focus F and pole of the mirror P, i.e., f > u > 0. An enlarged, virtual and erect image is formed behind the mirror. A real image (always inverted) is the one through which the rays of light actually pass after reflection from concave mirror and which can be formed on a screen.
