Which of the following properties of light does not depend upon the nature of the medium?
Correct answer: D. Frequency
- A. Velocity
- B. Wavelength
- C. Amplitude
- D. Frequency
Explanation
Frequency is fixed by the source and remains unchanged when light enters a new medium; velocity and wavelength change according to the medium's refractive index.

The more specific you are, the faster it gets fixed. A source beats an opinion.

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.
