Michelson devised the formula to calculate the speed of light:
Correct answer: C. c=16fd
- A. c=4fd
- B. c=8fd:
- C. c=16fd
- D. c=5fd/2
Explanation
Michelson's formula to calculate the speed of light is c=2d×f, where c is the speed of light, d is the distance traveled by light, and f is the frequency of the light source.

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.
