The locus of all points having the same phase of vibration is known as
Correct answer: D. Wave front
- A. Amplitude
- B. Trough
- C. Crest
- D. Wave front
Explanation
The correct answer is Wave front. A wave front is defined as the locus of all points in a medium that have the same phase of vibration. This concept helps in visualizing how waves propagate through space. The other options are different characteristics of waves: Amplitude is the height of the wave, Trough is the lowest point of the wave, and Crest is the highest point, none of which relate to the phase of vibration.

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.
