In case of three plane mirrors meeting at a point to form a corner of a cube, if incident light suffers one reflection on each other
(A) The emergent ray is antiparallel to incident one
(B) The emergent ray is perpendicular to incident one
(C) The incident ray can not emerge
(D) None of these
This question is very hard to understand. "if incident light suffers one reflection on each" or on "each other"??
