To get a full destructive interference
between two waves travelling in the
same direction, a time delay of At = 3
sec is created between the two
waves. The frequency of each
individual wave is:
O f = 1/4 Hz
f = 1/6 Hz
f = 1/5 Hz
f = 1/3 Hz
Two strings, A and B, have respective
mass densities µA and µB
respectively. The linear mass density,
µB, of string-B is nine times that of
string-A (µB = 9HA). If both strings
%3D
have the same fundamental
frequency when kept at the same
tension, then the ratio of their
lengths LA / LB is equal to:
9.
