Two sources of light are coherent if they emit rays of

Correct answer: C. same wavelength with constant phase difference

  • A. same wavelength
  • B. same amplitude of vibration
  • C. same wavelength with constant phase difference
  • D. same amplitude and wavelength

Explanation

Explanation: Coherent sources of light emit waves with the same wavelength and a constant phase difference. This condition is crucial for the formation of interference patterns.

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.
