Michelson's interferometer is usually used to determine:

Correct answer: A. Wavelength of light

  • A. Wavelength of light
  • B. Velocity of light
  • C. Amplitude of light
  • D. Dispersion of light

Explanation

Michelson interferometer is primarily used to study the interference of light waves and determine their wavelength. This is achieved by analyzing the interference patterns produced by splitting and recombining a light beam using mirrors. The other options such as measuring velocity, amplitude, or dispersion of light are not the main objectives of Michelson's interferometer.

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.
