Seiche
A seiche is an oscillating standing wave in a body of water. The term seiche pronounced saysh) can be understood by the sloshing of water back and forth in a swimming pool. The same phenomenon happens on a much larger scale in vast bodies of water including bays and lakes. A seizure can happen in any enclosed or semi-enclosed body of water.
Question
![### Harmonic Motion in a Stretched String
**Problem Statement:**
A stretched string fixed at each end has a mass of **47.0 g** and a length of **8.20 m**. The tension in the string is **40.0 N**.
**Questions:**
**(a) Determine the positions of the nodes and antinodes for the third harmonic.**
*(Enter your answers from smallest to largest distance from one end of the string.)*
**Nodes:**
- [ ] m
- [ ] m
- [ ] m
- [ ] m
**Antinodes:**
- [ ] m
- [ ] m
- [ ] m
**(b) What is the vibration frequency for this harmonic?**
- [ ] Hz
**Explanation:**
For a string fixed at both ends, nodes and antinodes are formed at specific positions during harmonic vibrations. Nodes are points where there is no motion, and antinodes are points where the motion is maximum.
**Third Harmonic:**
In the case of the third harmonic, the string will have three antinodes and four nodes, including the two fixed ends. The positions of these nodes and antinodes are determined based on the length of the string and the harmonic.
**Steps to Find the Positions and Frequency:**
1. Calculate the position of nodes and antinodes:
- For the n-th harmonic of a string of length \(L\), the positions of the nodes are at distances of \( L/n \), \( 2L/n \), ..., \( n-1)L/n \).
- The positions of the antinodes are at distances of \( L/(2n) \), \( 3L/(2n) \), ..., \( (2n-1)L/(2n) \).
2. Calculate the vibration frequency:
- The fundamental frequency \( f_1 \) of a stretched string is given by \( f_1 = \frac{1}{2L} \sqrt{\frac{T}{\mu}} \), where \( T \) is the tension and \( \mu \) is the linear mass density (\( \mu = \frac{m}{L} \)).
- For the n-th harmonic, the frequency \( f_n = n \times f_1 \).
By following these steps, you can determine the required positions for nodes and antinodes, as](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa5d0ed69-4925-4403-a796-f6681910a505%2F1eda67de-3e49-4d4b-a2a5-56fb59e5f64c%2F16i930f_processed.png&w=3840&q=75)
