Question

how do we observe the image formed by a concave (¡¡】convex reflecting surface
​

Answer 1

Answer:

it is also known as a converging mirror. When the concave mirror is placed very close to the object, a magnified and virtual image is obtained. But if we increase the distance between the object and the mirror then the size of the image reduces and a real image is formed. So the image formed by the concave mirror can be small or large and it can also be real or virtual.

Answer 2

Answer:

The concave mirror form an image and that depends on the two parameters: the object distance and the focal length of the mirror.

If the objects is placed between the pole and the focus of a concave mirror , a magnified and erect virtual is found to be formed.
