In the shadow of a ball, the central portion appears bright. This happens due to
Correct answer: B. Diffraction
- A. Interference
- B. Diffraction
- C. Polarization
- D. Refraction
Explanation
Explanation: The phenomenon where the central portion of the shadow of an opaque object appears bright is due to diffraction. Diffraction causes the bending of light around the edges of the object, and constructive interference in the central region results in brightness.

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.
