Q. Two vertical plane mirrors are inclined at an angle of ${60}^o$ with each other. A ray of light travelling horizontally is reflected first from one mirror and then from the other mirror. Then the resultant deviation is

Q. Two vertical plane mirrors are inclined at an angle of ${60}^0$ with each other. A ray of light travelling horizontally is reflected first from one mirror and then from the other. The resultant deviation is

Q. Two plane mirrors are inclined to each other with their reflecting faces making acute angle. A light ray is incident on one plane mirror. The total deviation after two successive reflections is

Q. Two plane mirrors are inclined at an angle of ${60}^o$ with each other. An incident ray hits one of the mirror at an angle of ${80}^o$ with the normal. Its angle of deviation after two reflections is

Q. Two plane mirrors are inclined at an angle $80$ degrees. A Ray of light is incident on one of the Mirrors. The ray after two reflection will undergo total deviation of:
