Understanding Reflection of Light
When light reflects off a surface, it follows the law of reflection, which states:
- The angle of incidence is equal to the angle of reflection.
Given Information
- Angle of incidence (i) = 50 degrees.
Calculating the Angle of Reflection
- According to the law of reflection:
- Angle of reflection (r) = Angle of incidence (i) = 50 degrees.
Finding the Angle Between Incident and Reflected Rays
To find the angle between the incident ray and the reflected ray, consider the following:
- The angle between the incident ray and the normal (a perpendicular line to the surface) is 50 degrees.
- The angle between the reflected ray and the normal is also 50 degrees.
Since the incident ray and the reflected ray are on opposite sides of the normal, the total angle between them can be calculated as follows:
- Total angle between the incident ray and reflected ray = Angle of incidence + Angle of reflection
- Total angle = 50 degrees + 50 degrees = 100 degrees.
Conclusion
Thus, the angle between the incident ray and the reflected ray is 100 degrees, making the correct answer option (b) 100 degrees.

- The angle between the reflected ray and the normal is also 50 degrees.
Since the incident ray and the reflected ray are on opposite sides of the normal, the total angle between them can be calculated as follows:
- Total angle between the incident ray and reflected ray = Angle of incidence + Angle of reflection
- Total angle = 50 degrees + 50 degrees = 100 degrees.
Conclusion
Thus, the angle between the incident ray and the reflected ray is 100 degrees, making the correct answer option (b) 100 degrees.
