A stretched string has a fundamental frequency of 165 Hz. Someone nearby sings a note at a frequency of 495 Hz. As a result, the string: 1. Will begin to vibrate 2. Will not vibrate at all 3. Might vibrate…depends on the song 0 of 250 30
The sources A and B are identical, emitting waves with wavelngth . Waves from each source travel along the path shown. What distance smallest X is necessary for the waves to be completely out of phase at the Line shown? A D B X X 1. 2. 3. 4. 5. X= D/2 X= /4 X= /2 0 of 250 30
The two sources A and B are identical, emitting waves of wavelength . They are separated by a distance D=1. 5 , equally spaced from the origin along the y-axis. What type of interference occurs at point P 1? 1. 2. 3. 4. Fully destructive Mostly destructive Fully constructive Depends on the distance of P 1 from the origin P 2 D A P 1 B 0 of 250 30
