We can hear sound around the corner but cannot see because of
Correct answer: B. Diffraction
- A. Interface
- B. Diffraction
- C. Polarization
- D. Dispersion
Explanation
Diffraction is the bending of waves around obstacles or through openings. Sound waves can diffract around corners, allowing us to hear sound even when we cannot see the source.

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.
