Question

Under which conditions do both convex and concave mirrors form virtual images? State whether or not each can form a real image.If the mirror can form a real image, describe how this occurs.

Answer 1

Concave mirror​s can make a real image.when the object is away from the mirror it is called real image and when the object is closer to the mirror it is called virtual mirror.

Answer 2

Answer:

In case of concave mirror the real image will form when object is placed at a distance which is more than the focal length of the mirror.

So here if more distance from the mirror then we will have more chance to get real image.

Now if we wish to have virtual image using concave mirror then we can say that object must have to place at distance less than the focal length of the mirror.

So if object is placed closer to the mirror then the image must be virtual and erect.

Now in case of convex mirror we will say that image formed will be virtual image in all cases because the focal length of the convex mirror is always positive so it will always form virtual image.

So here concave mirror if distance of object is less than the focal length then it will form virtual image and if the distance of object is more than focal length then it will form real image. While is convex mirror it will always form virtual image.
