omprehension Q 7 to Q 9 Sound sources S and S are located at x and x respectively The sources produce tones with the same phase and amplitude The frequency can be varied from 175 Hz to 625 Hz but both speakers have the same frequency Assume that the pressure variation amplitude po does not decrease with distance from the source Use 340 m s for the velocity of sound in air and x 0 850 m y4 A p 2p cos 2nft sin 2TX 2 S Xo Both S S emit sound of frequency 300 Hz and a detector is moved along x axis How many minima will the detector observe in going from S S A 6 B 4 C 8 D 10 For which frequencies in the above range is minimum sound intensity heard at all points along the x axis with x Xo A 200 500 Hz B 300 500 Hz C 300 400 Hz D 200 400 Hz Consider the region on the x axis between the two sound sources S and S Which of the following equations is the correct equation for the resultant sound wave pressure for all points between S and S on x axis B p 2po sin 2nft cos 2TX C p 2p sin 2nft cos X0 X D None of these 2TX 32
