What is the phenomenon in which a beam of light spreads out as it passes through a narrow aperture or around an obstacle?
A. Refraction
B. Polarization
C. Diffraction✓ Correct Answer
D. Interference
💡 Solution & Explanation
Diffraction is the phenomenon where wave fronts bend and spread when encountering an obstacle or passing through a narrow slit comparable in size to their wavelength. Other phenomena like refraction and interference involve bending through medium changes or superposition of multiple waves respectively. Basic wave optics principles are frequently tested in general science sections.
