what is the wavelength of a wave that has a speed of 350 meters/second and a frequency of 140 hertz? meters

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 the given values

Given $v = 350$ m/s and $f = 140$ Hz, we substitute these values into the formula: $\lambda=\frac{350}{140}$.

Step4: Calculate the result

$\frac{350}{140}=2.5$ m.

Answer:

2.5
