Consider a rope fixed at both ends under tension so that it is horizontal (i.e., assume the rope is along the xaxis, with gravity acting along the zaxis). Now the right end is continually oscillated at high frequency n (say n=100 Hz) horizontally and in a direction along the rope; amplitude of oscillation is negligible. The oscillation travels along the rope and is reflected at the left end.
Let the total length of rope be I, total mass be m and the acceleration due to gravity be g.
After initial phase (say a minute or so), the rope has (BLANK1)_ wave, which is_(BLANK2)__in nature. It results from superposition of left travelling and right traveling _(BLANK3) waves. This resulting wave has a frequency__(BLANK4) _ that of oscillation frequency nu, Simpy&fmensional analysis indicates that the frequency of can be of the form:___(BLANK5)__.
