Mirage is an example of ___________?
Correct answer: C. Refraction and total internal reflection of light
- A. reflection of light
- B. refraction of light
- C. Refraction and total internal reflection of light
- D. Scattering of light
Explanation
A mirage forms when light travels through air layers at different temperatures and densities, causing refraction, often followed by total internal reflection in the warmer near-ground layer. The observer therefore sees a displaced image that may resemble water. Students may choose simple refraction because they recognize bending in unequal air layers but omit the internal reflection involved in the common mirage description.

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.
