you are given three mirror of equal size concave convex and planr how will you idemtify them without touching their surface?
Answers
Explanation:
If the image formed is of same size as our face but laterally inverted for all positions, then it is a plane mirror.
If the image formed is erect and enlarged initially but gets inverted as the face is moved away, then it is a concave mirror.
If the image formed is erect and smaller in size for all positions then it is a convex mirror.
Hope it helps uh!!
Explanation:
We will identify the mirrors without touching as follows :
•CONVEX MIRROR :
We will identify the convex mirror by putting an object in front of it. If it will be a convex mirror then we will find that the image is always smaller than the object, doesn't matter where the object is put.
•PLAN MIRROR :
Similarly, we will identify the plan mirror by putting an object in front of it. If it will be a plan mirror then we will find that the size of image is always equal to the size the object, doesn't matter where the object is put.
•CONCAVE MIRROR :
The mirror left is the concave mirror.
