The new position of a wave front time t is determined by using:
Correct answer: A. Huygen's principle
- A. Huygen's principle
- B. Michelson interferometer
- C. Young's double slit experiment
- D. Bragg's formula
Explanation
Huygen's principle is the correct answer because it describes how each point on a wave front can act as a source of secondary spherical waves, with their envelope representing the new position of the wave front at a later time. The other options, such as the Michelson interferometer, Young's double slit experiment, and Bragg's formula, are not directly related to determining the new position of a wave front as described by Huygen's principle.

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.
