To decrease the fundamental frequency of streched string at both ends fix one might
Increase Wave velocity
Decrease Liner momentum
After increasing length freq. decreases
Reflection of wave-free end -
1) If the end of the string is free to move vertically, the free end overshoots twice the amplitude.
2) At boundary all or part of it is reflected .
3) When reflected from free end, the pulse is not inverted.
