Does diffraction occur only in light not in sound ? Give reason

i hope my answer is correct

Explanation: Let us start with the explanation of this question by the basic formula for diffraction for the Young's Slits Experiment :
sin (∅) = λ/d
where ∅ is the angle of diffraction
λ is the corresponding wavelength
d is the slit spacing
As we can clearly see, λ is directly proportional to the sine of angle of diffraction ∅. This means, greater the wavelength, greater the diffraction. Therefore, it is quite clear now that diffraction in sound is much more magnified in our daily lives than the diffraction of light. This is because the wavelength of sound is of the order 1 meter which means that objects of the size of a meter (which commonly exist around us) will diffract sound strongly.
On other hand, for light, we need objects in the micron scale to see the pronounced effect of light's scattering.
