If the figure $$M_1$$ and $$M_2$$ are two fixed mirrors as shown. If the object 'O' moves towards the plane mirror, then the image I (Which is formed after two successive reflections from $$M_1$$ and $$M_2$$ respectively ) will move:
with zero velocity
at the object itself
The correct option is D at the object itself image of concave mirror becomes object for plane mirror.
second reflection from the plane mirror ,image is formed at the same distance from the plane as is the distance of the object.
therefore second image is formed at the object itself
