what is the speed of a wave with a frequency of 2 hz and a wavelength of 87 m? 0.023 m/s 43.5 m/s 89 m/s 174 m/s
Answer
Explanation:
Step1: Recall wave - speed formula
The formula for the speed of a wave is $v = f\lambda$, where $v$ is the speed, $f$ is the frequency, and $\lambda$ is the wavelength.
Step2: Substitute given values
Given $f = 2\ Hz$ and $\lambda=87\ m$. Substitute into the formula: $v=2\times87$.
Step3: Calculate the speed
$v = 174\ m/s$.
Answer:
174 m/s
