Hi everyone, this is the problem based on formation of image by convex mirror.
00:32
In this problem it is given, explain can image form by convex mirror ever be larger than size of object? let us hear the explanation for real object in front of convex mirror image firm never be larger than size of the object because convex mirror diverge the reflected rays.
02:45
Let us hear the explanation with the help of radar.
02:50
Suppose this is the convex mirror principal axis focus point center of curvature.
03:10
In front of it this is the object.
03:17
This is a v is object.
03:23
Take a ray of light parallel to the principal axis.
03:27
It diverge through the focus point.
03:40
Take another ray of light passing through the center of curvature.
03:45
It retrace its original path.
03:50
So reflected ray appears to be diverging through this point.
03:54
So at this point we will get image a -b -d -s.
03:59
So a -d -b -d -s is less than a -v.
04:03
For object is to be from infinity to zero.
04:12
However, for virtual object, the image formed by convex mirror, may have the size of the object more than that of the image, sorry, more than that of the object.

Let us try to understand with the help of the ray diagram...
