Diffraction is:
ABending of waves around obstacles or edges
BPolarization
CSplitting of light into colors
DTotal reflection
Answer & Solution
Correct answer: A. Bending of waves around obstacles or edges
Diffraction: when waves encounter an obstacle or aperture, they bend and spread. Effect more pronounced when aperture size is comparable to wavelength. Single-slit diffraction gives central bright maximum with secondary minima/maxima.
