In Michelson interferometer, wavelength of light is given by the expression:
Correct answer: C. P = 1/2 mλ
- A. P = mλ
- B. P = 2 mλ
- C. P = 1/2 mλ
- D. None of these
Explanation
The expression for the wavelength of light in Michelson's interferometer is given by P = 1/2 mλ. This formula takes into account the specific setup and principles of Michelson's interferometer. The other options provided do not accurately reflect this relationship, leading to their incorrectness.

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.
