Michelson calculated the speed of light using the instrument
Correct answer: C. Interferometer
- A. Spectrometer
- B. Galvanometer
- C. Interferometer
- D. None of these
Explanation
Michelson used an interferometer to measure the speed of light. His method involved measuring the time taken for light to travel a known distance.

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.
