Question

Standing waves are produced by the superposition of two waveswith a) The same amplitude, frequency, and direction ofpropagation. b) The same amplitude, frequency, and opposite propagationdirections. c) The same amplitude, direction of propagation, but differentfrequencies. d) The same amplitude, different frequencies, and oppositedirection of propagation. the answer is b. I wanna know why.. Explain plz..

Explanation / Answer

I would go with b) The same amplitude, frequency, and opposite propagationdirections. Why? Since this wave modes arise from the combination of reflectionand interference such that the reflected waves interfereconstructively with the incident waves. A pcture is worth 1000 words? Clickhere Have fun
