1.	How will you arrange the two plane mirros so that whatever may be the angle of incidence, the incident ray and the reflected ray from the two mirrors will be paralle to each other ?
Answer» The two PLANE mirros should be parallel toeach other. The two plane mirros should be INCLINED at an ANGLE of `30^@` The two plane mirrors should be inclined at an angle of `30^@` The two plane mirros should be inclined at an angle of `45^@`. Answer :The two plane mirros should be PERPENDICULAR to each other.
