When two mirroes are inclined at an angle of `60^(@)` with each other, find the glancing angles and angle of deviations at both the mirrors if the angle of incidence of a light ray is `45^(@)` . Draw its ray diagram. |

Answer» `i_(1)=r_(1)=45^(@)` `i_(2)=r_(2)=15^(@)` Glancing angle at `M_(1)=90-i_(1)=90-45^(@)` `" "=45^(@)` Glancing angle at `M_(2)=90-i_(2)=90-15` `" "=75^(@)` Angle of deviation at `M_(1)=180-2i_(1)=90^(@)` Angle of deviation at `M_(2)=180-2i_(2)=150^(@)` |
