8. 7. For the diagram to the right, two waves are going to overlap. Rank the interference patterns from the largest combined amplitude to the smallest combined amplitude. B A n+n n+u Largest to smallest. C D n + n n + List all of the letters that are destructive interference. bonoq sis SH S =7 2.0 A standing wave pattern is shown on a string that has a length of 2 m. a) How many nodes are present in the diagram? b) How many antinodes are present in the diagram? = 2. 2 meters c) If the frequency to cause this pattern is 4 Hz, what is the speed of the wave on the string?
