प्रश्न
Where would the image be formed by a convex mirror if the object is placed:
between infinity and pole of the mirror?
Draw labelled ray-diagrams to show the formation of image in both the case.
उत्तर
Following are the ray-diagrams to show the formation of image, by a convex mirror, of the same object but in different locations:
between infinity and pole of the mirror
The image will be virtual, magnified and behind the mirror when the object is between the infinity and focus of the mirror.
