Answer:
ν = 1483.939 m/s
Explanation:
Wave propagation speed (ν):
- ν = λ / T
∴ Wavelength ( λ ) = 4.25 m
∴ Period ( T ) = 1 / f
∴ frequency ( f ) = 349.2 Hz ( s-1 )
⇒ T = 1 / 349.2 s-1
⇒ T = 2.864 E-3 s
⇒ ν = (4.25 m) / (2.864 E-3 s)
⇒ ν = 1483.939 m/s
Answer: The wave speed of the given sound wave is [tex]1.48\times 10^3m/s[/tex]
Explanation:
Wave speed is defined as the product of its wavelength and frequency.
Mathematically,
[tex]\text{Wave speed}=\lambda\times \nu[/tex]
where,
[tex]\lambda [/tex] = wavelength of the wave = 4.25 m
[tex]\nu [/tex] = frequency of the wave = 349.2 Hz = [tex]349.2s^{-1}[/tex]
Putting values in above equation, we get:
[tex]\text{Wave speed}=4.25m\times 349.2s^{-1}\\\\\text{Wave speed}=1484.1m/s=1.48\times 10^3m/s[/tex]
Hence, the wave speed of the given sound wave is [tex]1.48\times 10^3m/s[/tex]
