The speed of light in vacuum depends upon:
Correct answer: D. None of these
- A. Time period
- B. Frequency
- C. Wavelength
- D. None of these
Explanation
In vacuum c is a universal constant independent of the light's frequency, wavelength or period. Frequency and wavelength relate via c = fλ, but c itself is fixed.

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.
