This question is for a conceptual physics class (no trig involved).
1. The wave speed on a tightened guitar string is 880 m/s. What is the shortest length of string that will produce standing waves of 440-hertz frequency? (Be very CAREFUL!)
a. 0.5m
b. 1.0m
c. 1.5m
d. 2.0m
e. none of these
2. velocity = frequency x wavelength
3. 880/440 = 2m
Is 2m correct? I ask because of the warning the instructor placed at the end of the question leads me to believe that the answer isn't so straightforward. If it is incorrect, can you offer any pointers as to what I did wrong or did not take into consideration?
Thanks
