Which of the following phenomenon is not common to sound and light waves?

Explanation

For diffraction of a wave, the size of particle/obstacle/aperture should be of the order of wavelength of wave. Since the average wavelength of visible light is of the order of `10^(-6)`m and obstacle/aperture of this size are rare, therefore, diffraction of light is not common. But in case of sound, the wavelength of waves is `1-2`m. and obstacle/aperture of this size is readily available, therefore diffraction of sound is quite common.
