Which of the following properties of light does not change with the nature of the medium?
Correct answer: C. Frequency
- A. Speed
- B. Wavelength
- C. Frequency
- D. All three
Explanation
The frequency of light does not change with the change of medium because it depends on the frequency of the source of light. The speed and wavelength, however, do change with different media.Refraction is shown by light when entering from one medium to another because of the change in speed and wavelength of light at the interface.

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.
