Question

what is the speed of a wave that has a wavelength of 2m and a frequency of 3200hz.
64 m/s
6400 m/s
1,600 m/s
16m/s

Explanation:

Step1: Recall wave speed formula

The formula for wave speed is $v = f \times \lambda$, where $v$ is wave speed, $f$ is frequency, and $\lambda$ is wavelength.

Step2: Substitute given values

Given $\lambda = 2\ \text{m}$, $f = 3200\ \text{Hz}$, substitute into the formula:
$v = 3200\ \text{Hz} \times 2\ \text{m}$

Step3: Calculate the result

$v = 6400\ \text{m/s}$

Answer:

B. 6400 m/s
