A steady sound with a frequency of f = 750 Hz is produced by a source located far from an open doorway set in a sound-absorbing wall. The sound waves pass through the w = 1.16 m-wide doorway. (Assume the speed of sound is 343 m/s.) (a) If a person walks parallel to the wall beyond the open doorway, how many diffraction minima will she encounter? 4 (b) What are the angular directions (in degrees) of these diffraction minima? (Enter the magnitudes from smallest to largest starting with the first answer blank. Enter NONE in any remaining answer blanks. Do not enter any duplicate numerical values.) smallest = -52.0 x Apply the condition for diffraction minima. You will need to calculate the wavelength of the sound. Recall that sin(O) s 1. º + -23.2 x Apply the condition for diffraction minima. You will need to calculate the wavelength of the sound. Recall that sin(O) = 1.° + 23.2 x Apply the condition for diffraction minima. You will need to calculate the wavelength of the sound. Recall that sin(O) s 1. º largest + 52.0 x Apply the condition for diffraction minima. You will need to calculate the wavelength of the sound. Recall that sin(O) s 1. º
