Question

question 10 of 28. sound travels at 340 m/s in dry air at room temperature. what is the wavelength of sound waves with a frequency of 440 hz under those conditions? a. 1.3 m b. 150 km c. 0.77 m d. 2.3 mm

Explanation:

Step1: Recall wavelength formula

$\lambda = \frac{v}{f}$

Step2: Substitute values (v=340 m/s, f=440 Hz)

$\lambda = \frac{340}{440} \approx 0.773 \, \text{m}$

Answer:

C. 0.777 m
