1) 7/8p - 4 = 10

7/8p - 4 + 4 = 10 + 4

7/8p =14

0.875p = 14

0.875p/0.875 = 14/0.875

p=16

did i do it right?

The question is: when two waves interfere constructively or destructively, is there any gain or loss in energy?
The answer is that the total energy of the pair of waves remains the same because energy missing from zones of destrctive interference appears in zones of constructive interference.
However, if the standing wave has ONLY constructive of destructive interferance, what happens? The answer does not touch on that. Why is there no gain or loss in energy?
