In total internal reflection, light travels:
Correct answer: A. From denser to rarer medium
- A. From denser to rarer medium
- B. From rarer to denser medium
- C. From vacuum to glass
- D. From air to glass
Explanation
Total internal reflection occurs only when light moves from a denser medium (like water or glass) to a rarer one (like air) and the angle of incidence exceeds the critical angle.

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.
