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 freuqency `9//pi` rps. The light reflected by the mirror is received on the wall W at a distance 10 m from the axis of rotation. When the angle of incidence becomes `37^(@)`, the speed of the sopt (a point) on the wall is
