Figure 7.88 shows a stretched string of length L and pipes of length L,2L,L/2andL/2 in options (a) , (b), (c ) and (d) respectively . The string ‘s tension is adjusted until the speed of waves on the string equals the speed of sound waves in the air . The fundamental mode of oscillation is the set up on the string . In which pipe will the sound produced by the string cause resonance ?
