Standing waves are produced in a string 16 \(\mathrm{m}\) long. If there are 9 nodes between the two fixed ends of the string and the speed of the wave is \(32 \mathrm{~m} / \mathrm{s}\), what is the frequency of the wave?
- A \(5 \mathrm{~Hz}\)
- B \(10 \mathrm{~Hz}\)
- C \(30 \mathrm{~Hz}\)
- D \(20 \mathrm{~Hz}\)
Answer & Solution
Correct Answer
(B) \(10 \mathrm{~Hz}\)
Step-by-step Solution
Detailed explanation
Given, length of spring, \(l=16 \mathrm{~m}\) speed of wave, \(v=32 \mathrm{~m} / \mathrm{s}\) and total number of nodes between the two fixed ends of the string \(=9\) \(\therefore\) Total number of segments of vibrations between fixed ends, \(p=9+1=10\) \(\therefore\)…
