Two plane mirrors one of which is horizontal are inclined at angle X ....
Introduction:
Two plane mirrors are inclined at an angle X, with one mirror being horizontal and the other non-horizontal. We need to find the value of X when a ray of light incident on the horizontal mirror parallel to the non-horizontal mirror reflects in such a way that it emerges out in a horizontal direction.
Explanation:
To solve this problem, let's consider the path of the light ray and analyze the reflection process step by step.
Step 1: Incident Ray:
- The incident ray is parallel to the non-horizontal mirror.
- Since the reflection from the second mirror emerges out in a horizontal direction, the incident ray should be directed towards the non-horizontal mirror at an angle of 45 degrees from the horizontal.
Step 2: Reflection from the First Mirror:
- The incident ray strikes the horizontal mirror.
- According to the law of reflection, the angle of incidence is equal to the angle of reflection.
- As the incident ray is parallel to the non-horizontal mirror, the angle of incidence on the horizontal mirror is 45 degrees.
Step 3: Reflection from the Second Mirror:
- After reflection from the horizontal mirror, the ray reaches the non-horizontal mirror at an angle of 45 degrees.
- According to the law of reflection, the angle of incidence is equal to the angle of reflection.
- Since the ray emerges out in a horizontal direction, the angle of reflection on the non-horizontal mirror should be 0 degrees.
Step 4: Finding the Angle X:
- The angle between the two mirrors is X.
- When the ray reflects from the horizontal mirror at 45 degrees and then from the non-horizontal mirror at 0 degrees, the total change in angle is X.
- So, X = 45 degrees - 0 degrees = 45 degrees.
Conclusion:
The value of X is 45 degrees.

The value of X is 45 degrees.
