Question

a note is played at 256 hz. what is the wavelength of this note if the speed of sound is 343 m/s? use wavelength = \frac{speed of sound}{frequency}.
a. 1.54 meters
b. 0.85 meters
c. 1.34 meters
d. 1.44 meters

Explanation:

Step1: Substitute values into formula

Given \( \text{Speed of Sound} = 343\ m/s\) and \( \text{Frequency}=256\ Hz\), use \( \text{Wavelength}=\frac{\text{Speed of Sound}}{\text{Frequency}}\). So, \( \text{Wavelength}=\frac{343}{256}\).

Step2: Calculate the result

\(\frac{343}{256}= 1.33984375\approx1.34\) (rounded to two decimal places).

Answer:

C. 1.34 meters
