PRACTICE / String harmonics
Adjacent resonances reveal the fundamental
A uniform taut string fixed at both ends shows two adjacent resonance frequencies of 360 Hz and 480 Hz.
How many displacement antinodes are present in the 480 Hz mode?
Organize the givens & assumptions
- Adjacent resonances: 360 Hz and 480 Hz
- Both ends fixed
Ideal uniform string, negligible stiffness and damping; no resonance is skipped between the two stated peaks.
- A
- B
- C
- D
