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 high wall of water moving towards the shore from the ocean is called a

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?

5 m long ladder is placed leaning towards a vertical wall such that it reaches the wall at a point 4 m high. If the foot of the ladder is moved 1.6 m towards the wall, then find the distance by which the top of the ladder would slide upwards on the wall.

Figure shows a cubical room ABCD with the wall CD as a plane mirror. Each side of the room is 3 m . We place a camera at the midpoint of the wall AB . At what distance should the camera be focussed to photograph an object placed at A.
