Question

name the mirror which can show the size of the object of the object to be double of its original size ​

Answer 1

Answer:

convex mirror............

Answer 2

Answer:

Hey, there is no such mirror as such.

But a concave mirror shows a magnified image of the object , but the magnification depends on the distance between the object and the mirror. So if the distance can be adjusted such that the image size is double the original size of the object then it might be possible.
