 Sound wave have frequencies 20 Hz to 20 kHz. The corresponding wavelengths are 15m and 15mm, respectively. Diffraction effects are seen if there are slits of width α such that.

α : λ

For light waves, wavelengths  10–7m. Thus diffraction effects will show when

α : 10–7 m.

whereas for sound they will show for

15mm < α < 15m .
