a flute plays a note with a frequency of 266 hz. what is the speed of sound if the wavelength is 1.3 m?\n102 m/s\n205 m/s\n346 m/s\n692 m/s
Answer
Explanation:
Step1: Recall wave - speed formula
The formula for the speed of a wave is $v = f\lambda$, where $v$ is the speed of the wave, $f$ is the frequency, and $\lambda$ is the wavelength.
Step2: Substitute given values
Given $f = 266\ Hz$ and $\lambda=1.3\ m$. Substitute into the formula: $v=266\times1.3$.
Step3: Calculate the result
$v = 345.8\ m/s\approx346\ m/s$.
Answer:
C. 346 m/s
