OB strikes the other mirror at P and finally emerges parallel to OA after twe reflections then is equal to Techno Text Book angle 'e' as shown in figure a ray parallel to А a) 60 1) 00 A ray of light is incident at so on the middle of one of the two mirrors arranged reflected back to the first mirror, making an angle of incidence of 2) 60" 3) 70 4) 80 10. Two vertical plane mirrors are inclined at an angle of 60" 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 2) 120 3) 180° 41 240° 1) 60 1) 50 166 26 HO LEVEL 311.
