Question

3/10
if a wave is traveling at 60m/s and has a wavelength of 3m. what is the frequency?
18hz
180hz
10hz
20hz

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

Step2: Substitute given values

Substitute $v = 60\,\text{m/s}$ and $\lambda = 3\,\text{m}$ into the formula:
$f = \frac{60}{3}$

Step3: Calculate the result

Perform the division to find the frequency.

Answer:

D. 20Hz
