question 33 of 33
a wave moving with a speed of 3.0 m/s has a frequency of 9 hz. what is the wavelength of the wave?
a. 12 m
b. 18 m
c. 0.33 m
d. 3.0 m

Explanation:

Step1: Recall wave - speed formula

The wave - speed formula is $v = f\lambda$, where $v$ is the speed of the wave, $f$ is the frequency, and $\lambda$ is the wavelength. We need to solve for $\lambda$.

Step2: Rearrange the formula

Rearranging $v = f\lambda$ for $\lambda$ gives $\lambda=\frac{v}{f}$.

Step3: Substitute values

Given $v = 3.0\ m/s$ and $f = 9\ Hz$, we substitute these values into the formula: $\lambda=\frac{3.0\ m/s}{9\ Hz}\approx0.33\ m$.

Answer:

C. 0.33 m
