Consider two ldentical interfering waves with wavelength A 0.4 m travelling in the positive x-direction. The two waves start at the same time but at different positions, l and x2 from an observer (x1 > x2). What should the path difference, AxX1-x2, etween the starting positions be in order for the two waves to differ in phase by ruo rad? O A FIU20 A V40 O 4x50m O Ax60m A string fixed at both ends has a node-to-node distance of 80 cm when it oscillates in the 3rd harmonic.

Consider two identical interfering waves with wavelength A= 0.4 m travelling in the positive x-direction. The two waves start at the same time but at different positions, x1 and x2 from an observer (x1 > x2). What should the path difference, AX x1- x2, between the starting positions be in order for the two waves to differ in phase by ruo rad? O Ax F1/20 m O 40 O Ax1/80 m O Ax1/50n O Ax1/60m A string fixed at both ends has a node-to-node distance of 80 cm when it oscillates in the 3rd harmonic. If this same string is set to oscillate in the 4th harmonic. then the new node-t node distance is: 48 cm 60 cm KO 40 cm 120 cm 80 cm
