Vedclass · Answer

(A) Diffraction is the bending of waves around the corners of an obstacle or through an aperture. The condition for significant diffraction is that the size of the obstacle or aperture $(a)$ must be comparable to the wavelength $(\lambda)$ of the wave, i.e., $a \approx \lambda$ or $\frac{a}{\lambda} \approx 1$.Since the wavelength of sound waves $(\lambda_s)$ is much larger than the wavelength of light waves $(\lambda_l)$, sound waves can easily diffract around common obstacles (like doors or walls) whose dimensions are in the range of meters.Conversely, light waves have very small wavelengths (in the range of $10^{-7} \, m$), so they only show noticeable diffraction when passing through extremely small apertures or around very fine edges.

Sound waves exhibit more diffraction than light waves because:
