A plane mirror M is arranged parallel to a wall W at a distance l from it. The light produced by a point source S kept on the wall is reflected by the mirror and produces a patch of light on the wall. The mirroo moves with velocity v towards the wall.
Which of the following statement(s) is`//`are correct?

Figure shows a torch sending a parallel beam of light fixed on a wall and a plane mirror which forms a spot on the wall. As the mirror moves towards the wall, the spot on the wall moves

A plane mirror 1 m high hangs on a wall.A man stnds at a distance 2 m away from the mirro.What is the height of the portion of the oposite wall in the room that can be seen by the man in the mirro,without changing the position of his head?The wall is 4m from the mirror.

In a dark room, a parallel beam of light falls on a plane mirror and another parallel beam of light falls on a white wall. The light reflected by the mirror can be seen only in a certain direction, but the reflected light from the wall can be seen from anywhere. Give reason.

A light ray I is incident on a plane mirror M .The mirror is rotated in the direction as shown in the figure by an arrow at frequency (9)/(pi) "rev"//"sec" ,The light reflected by the mirror is received on the wall W at a distance 10m from the axis of rotation .When the angle of incidence becomes 37^(@) find the speed of the spot (a point) on the wall?

A point source of light B,placed in front of the centre of a mirror of width d,hangs vertically on a wall.A man walds in front of the mirror along a line parallel to the mirror at a distance 2L from it as shown in the figure.The gretest distance over which he can see the image of the light source in the mirror is
