A string of length 0.5 m and mass per unit length 0.01 kg/m is under a tension of 16 N. What is the fundamental frequency of vibration?
Answer and explanation
Correct answer: C. 40 Hz
- Step 1: Wave speed m/s; the fundamental is Hz. Answer: 40 Hz. Why not the others: 80 Hz, 20 Hz and 50 Hz don't fit.
