Question
Two mirrors A and B are placed at right angles to each other. A ray of light incident on mirror A at an angle of 25° falls on mirror B after reflection. The angle of reflection for the ray reflected from mirror B would be
Solution
To find the angle of reflection for the ray reflected from mirror B, we can use the law of reflection, which states that the angle of incidence is equal to the angle of reflection.
- The ray of light incident on mirror A at an angle of 25°.
- According to the law of reflection, the angle of incidence on mirror A is equal to the angle of reflection.
- Therefore, the angle of reflection from mirror A is also 25°.
- The ray of light then falls on mirror B after reflection from mirror A.
- Since mirror B is placed at a right angle to mirror A, the angle of incidence on mirror B is 90° - 25° = 65°.
- According to the law of reflection, the angle of reflection from mirror B will also be 65°.
Therefore, the angle of reflection for the ray reflected from mirror B would be 65°.
