Diffraction effects are more easily detected in the case of sound waves than light waves because:
sound waves are longitudinal
sound waves have smaller wavelength
sound waves have larger wavelength
sound waves are transverse
The correct option is B sound waves have larger wavelength
Sound waves have higher wavelength and its wavelength is comparable to the dimension of opaque encounters in our daily life. Hence diffraction effects are more easily detected in the case of sound waves than light waves.
