A point source of light placed in a homogenous medium produce a
Correct answer: B. Spherical wave front
- A. Plane wave front
- B. Spherical wave front
- C. Cylindrical wave front
- D. Rectangular wave front
Explanation
The correct answer is a spherical wave front. This is because a point source of light in a homogeneous medium emits light uniformly in all directions, forming wave fronts that are spherical in shape as they propagate outward.Option A is incorrect because a plane wave front arises when the source is at a significant distance, causing the wave fronts to appear flat. Option C is incorrect as a cylindrical wave front would be generated by a linear source. Option D is incorrect because rectangular wave fronts do not naturally occur in the context of point sources in homogeneous media.

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.
