Question

1. what is the wavelength of a wave that has a speed of 30 m/s and a frequency of 6.0 hz? (1 point)

0.2 m
180 m
5 m
36 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 $v = 30\ m/s$ and $f = 6.0\ Hz$, we substitute these values into the formula: $\lambda=\frac{30\ m/s}{6.0\ Hz}$.

Step4: Calculate the result

$\lambda = 5\ m$.

Answer:

C. 5 m
