Diffraction occurs for all types of waves, including sound waves. high‐frequency sound from a distant source with wavelength 9.00 cm passes through a slit 12.0 cm wide. a microphone is placed 8.00 m directly in front of the center of the slit (point c). the microphone is then moved in a direction perpendicular to the line from the center of the slit. at what distances from c will the intensity detected by the microphone be zero?
