The following questions concern path difference in waves. A 97. Two sources S, and S, each produce coherent 3 m vibrations in water having a wavelength of 6 m and an amplitude of 10 cm. Three surrounding points are 12 m shown. The lines connecting Point Amplitude/ cm 6 m. C the sources to the points show 12 m the distance the points are A 0 from the sources. Complete the 4 m B 0 table: AS - AS, = 6 - 3 = 3 =072. D. 6 m C 20 BS - BS, = 9 - 6 =3 =02. D. CS, - CS, = 12 -12 = 0 = ( C
