Question

Explain why diffraction of sound is more common in daily experience than that of light.

Hint:

Condition for significant diffraction: Aperture/obstacle size \(\approx\) Wavelength. Since everyday objects (doors/windows) are about \(1 \text{ m}\) wide, they perfectly match sound wavelengths (\(\sim 1 \text{ m}\)) but fail to match light wavelengths (\(\sim 10^{-7} \text{ m}\)).
