Question

In what way diffraction of light waves differs from diffraction of sound waves?

Answer 1

Feature	Light waves	Sound waves
Wavelength	Very small (∼10−7 m)	Larger (∼10−3 to metres)
Diffraction Observability	Requires very narrow slits/gaps	Easily observed around obstacles
Practical example	Light bending around a sharp edge	Sound heard around corners
Extent of diffraction	Less noticeable due to the small wavelength	More noticeable due to a larger wavelength

Thus, sound waves diffract more easily around obstacles compared to light waves due to their longer wavelengths.
