a spherical wave front is that which has
Correct answer: B. a point source
- A. a source
- B. a point source
- C. an extended source
- D. none of these
Explanation
These are surfaces of constant phase (points in a wave where the wave is in the same state) that originate from a point source. This means the source of the wave is considered to be a single, infinitely small point in space

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.
