Following figure shows the multiple reflections of a light ray along a glass corridor where the walls are either parallel or perpendicular to one another. If the angle of incidence at point P is 30°, what are the angles of reflection of the light ray at points Q, R, S and T respectively
- 30°, 30°, 30°, 30°
- 30°, 60°, 30°, 60°
- 30°, 60°, 60°, 30°
