Question

4/10
what is the wavelength of a wave traveling at 1600m/s and a frequency of 400hz?
400m
4m
64m
640,000m

Explanation:

Step1: Recall wave speed formula

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

Step2: Substitute given values

$v = 1600\,\text{m/s}$, $f = 400\,\text{Hz}$
$\lambda = \frac{1600}{400}$

Step3: Calculate the result

$\lambda = 4\,\text{m}$

Answer:

B. 4m
