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.

In Michelson's interferometer, if movable mirror is displaced through distance equal to wavelength of monochromatic light then the number of bright fringes observed will be:
In Michelson's interferometer if the movable mirror is displaced through a distance of 0.05mm, 200 fringes are observed. The wavelength of light used in that case is:
In order to observe two successive bright or dark fringes in Michelson's interferometer, the movable mirror is displaced through a distance of:
For all practical purposes we consider that light travels in _:
When light traveling in one medium strikes the boundary of another medium a part of it is sent back in the same medium, this is known as _:
The gradual change of light, by which we receive light at dawn or after sunset, is due to _:
