Two plane mirrors, $$A$$ and $$B$$ are aligned parallel to each other, as shown in the figure. A light ray is incident at an angle of $$30^\circ$$ at a point just inside one end of $$A$$. The plane of incidence coincides with the plane of the figure. The maximum number of times the ray undergoes reflections (excluding the first one) before it emerges out is:

1. $$28$$
2. $$30$$
3. $$32$$
4. $$34$$
