Please use the equations provided to solve The speed of sound in a liquid or solid it’s much faster than the speed of sound in air, which is around 340 m/s.

**Vibrational Motion:**

- \( T = \frac{1}{f} \)
- \( \omega = 2\pi f \)

**Wave Equation:**

- \( v = f \lambda \)

**Standing Waves:**

- \( f_n = n f_0 \)
- \( \lambda_n = \frac{2L}{n} \)

**Wave Speed on a String:**

- \( v = \sqrt{\frac{T}{\mu}} \)
- \( \mu = \frac{\text{mass}}{\text{length}} \)

**Travelling Wave:**

- \( Y(x, t) = A \sin (kx - \omega t) \)

**Explanation:**

- **Vibrational Motion**: The period \( T \) is the reciprocal of frequency \( f \). The angular frequency \( \omega \) is given by \( 2\pi f \).
- **Wave Equation**: The wave speed \( v \) is the product of frequency \( f \) and wavelength \( \lambda \).
- **Standing Waves**: The frequency for a harmonic \( n \) is \( f_n = n f_0 \) and wavelength is given by \( \lambda_n = \frac{2L}{n} \), where \( L \) is the length of the medium.
- **Wave Speed on a String**: The speed \( v \) depends on tension \( T \) and linear density \( \mu \) (mass per unit length).
- **Travelling Wave**: The displacement \( Y(x, t) \) is described using amplitude \( A \) and wave numbers \( k \) and \( \omega \), representing spatial and temporal changes respectively.

Expert Solution
Step 1

Given: The speed of sound is 340 m/s. 

           The frequency is 2013 Hz. 

           The amplitude is 18.3 dB. 

           The steel with sound is 6956 m/s. 

To determine: The equation Y(x,t) 

The speed of sound is 

v=

where v is the speed, f is the frequency and λ is the wavelength 

Substitute 6956 m/s for v and 2013 Hz for f 

6956 m/s=2013 Hz×λλ=3.45 m

The wavelength is 3.45 m. 

The time period is 

T=1fT=12013 HzT=4.97×10-4 s
