spherical cavity with open ends is investigated theoretically and experimentally. On basis
of the diffraction theory of light，the intensity distribution of diffracted light is
deduced. And then，an image of the diffracted light is displayed by numerical calcu- lation. On the
other aspect，the acousto-optic diffraction is measured with our apparatus. The measured wavelength
of acoustic wave is coincided with that of excited spherical acoustic wave.
