If incident ray MP and reflected ray QN are parallel to each other, find the angle θ between the mirrors.
Correct answer: C. 90°
- A. 60°
- B. 45°
- C. 90°
- D. 180°
Explanation
When the incident ray and reflected ray are parallel, the angle between the mirrors is always 90° due to the Law of Reflection and geometric rules.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
