suppose there is a point object in front of a plane mirror. one incident ray from this point strikes mirror and reflect. Another light ray comes from some height which is above than the pointed object, strike the mirror and reflect. but when we extend first and second reflected ray it intersect at a point. will the image of the pointed object will form there. if not, why.
