Question

Is it possible to have a real image of a real object formed

1. By a plane mirror?
2. By a concave mirror?
3. By a convex mirror?

Answer 1

Step 1: In the case of a plane mirror,

1. The image formed by a plane mirror is always behind the mirror.
2. It means the image that forms by a plane mirror is a virtual image. So it is not possible to have a real image of a real object formed by a plane mirror.

Step 2: In the case of a convex mirror,

1. The image formed by a convex mirror is always behind the mirror.
2. It means the image that forms by a plane mirror is a virtual image. So it is not possible to have a real image of a real object formed by a convex mirror.

Step 3: In the case of a concave mirror,

1. A concave mirror formed a real image when the object is located at a distance greater than or equal to the focal length of that mirror.
2. A concave mirror formed a virtual image when the object is located at a distance less than the focal length of that mirror.
3. When an object is located at a distance greater than or equal to the focal length of a concave mirror, then the concave mirror formed a real image.
