what is the speed of a wave that has a frequency of 125 hz and a wavelength of 1.25 meters? express your…

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 $f = 125$ Hz and $\lambda=1.25$ m. Substitute into the formula: $v=125\times1.25$.

Step3: Calculate the result

$v = 125\times1.25=156.25$ m/s.

Step4: Round to the nearest whole number

Rounding 156.25 to the nearest whole number gives 156 m/s.

Answer:

156
