Question

a flute plays a note with a frequency of 266 hz. what is the speed of sound if the wavelength is 1.3 m?
102 m/s
205 m/s
346 m/s
692 m/s

Explanation:

Step1: Recall the wave - speed formula

The formula for the speed of a wave is \(v = f\lambda\), where \(v\) is the speed, \(f\) is the frequency, and \(\lambda\) is the wavelength.

Step2: Substitute the given values

Given \(f = 266\space Hz\) and \(\lambda=1.3\space m\). Substitute into the formula: \(v=(266\space Hz)\times(1.3\space m)\).

Step3: Calculate the value

\(v = 266\times1.3=345.8\approx346\space m/s\)

Answer:

C. 346 m/s
