Question

what is the wavelength of a sound wave with a frequency of 50hz if the speed of the sound is 350m/s?
17,500 m
.7m
17
7m

Explanation:

Step1: Recall wave speed formula

The relationship between wave speed $v$, frequency $f$, and wavelength $\lambda$ is $v = f\lambda$. Rearranged to solve for wavelength: $\lambda = \frac{v}{f}$

Step2: Substitute given values

Substitute $v=350\,\text{m/s}$ and $f=50\,\text{Hz}$ into the formula.
$\lambda = \frac{350}{50}$

Step3: Calculate the result

Perform the division to find the wavelength.
$\lambda = 7\,\text{m}$

Answer:

D. 7m
