Question

a wave moving at 2600m/s with a wavelength of 400m has what frequency?
1040000hz
6hz
6.5 hz
15hz

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 $v = 2600\,\text{m/s}$ and $\lambda = 400\,\text{m}$ into the formula:
$f = \frac{2600}{400}$

Step3: Calculate the result

Simplify the expression:
$f = 6.5\,\text{Hz}$

Answer:

C. 6.5 Hz
