The phenomenon of light bending around the corners of obstacles is known as _________.
Diffraction
Refraction
Reflection
Polarization
Diffraction
Diffraction is the phenomenon in which light waves bend around the sharp corners of an obstacle or aperture and spread into the geometrical shadow region. This occurs when the size of the obstacle or opening is comparable to the wavelength of the light wave.

Hearing sound from around a corner even when you cannot see the person speaking, because sound waves (and similarly light waves under the right conditions) bend around obstacles.
DIFFraction = DIFFusing or bending around obstacles.
asin╬╕=m╬╗ тАФ condition for diffraction minima for a single slit
According to Huygens-Fresnel principle, every point on a wavefront acts as a source of secondary wavelets. When a wavefront encounters an obstacle, the unobstructed parts of the wavefront continue to propagate, while the edges act as new sources, causing the waves to spread around the corners.
Diffraction is most pronounced when the obstacle size is comparable to the wavelength of the wave.
It demonstrates the wave nature of light.
It distinguishes wave optics from geometrical optics.
X-ray crystallography to determine crystal structures
Diffraction gratings used in spectrometers for wavelength analysis
Refraction refers to the bending of light when passing from one medium to another of different optical density.
Reflection is the bouncing back of light from a surface.
Polarization restricts the vibration of light waves to a single plane.
A is correct тАФ Diffraction is the bending of light around the corners of obstacles.
Remember that both diffraction and interference prove the wave nature of light, contrasting with the photoelectric effect which proves its particle nature.
