Hello everyone, for the solution of the question, let's check for the concave mirror using mirror formula 1 upon f is equals to 1 upon u plus 1 upon v.
00:11
So, for concave mirror, f is negative and u is also negative.
00:25
Therefore, the equation becomes 1 upon minus f is equals to 1 upon minus u plus 1 upon v.
00:33
Therefore, from here we get v is equals to f u divided by f minus u.
00:40
If f is greater than u, then v is positive, that is it forms virtual image.
00:58
And if f is smaller than u, this implies that v is negative.
01:05
Therefore, it forms real image.
01:11
Since it forms a real image as long as object distance is more than focal length.
01:18
Object distance is more than focal length and if object is placed between focus and mirror, then the image form will be virtual...
