Main Question or Discussion Point
Please could somebody explain why the fundamental frequency always has the biggest amplitude in comparison to the rest of the harmonics?
The anti- phase condition only occurs right at the termination. The relative phases of incident and reflected wave vary with distance and superposition produces the standing wave.Two waves traveling in opposite direction should die out according to super position principle (Zero amplitude). Then how standing waves are produced? Is this not a contradiction? Please help. thank you.
