Chapter 9.2, Problem 16R

To determine

The frequency of water wave.

Answer to Problem 16R

The frequency of water wave is $8\text{hertz}$ .

Explanation of Solution

Given data:

The speed of water wave is $4\text{m}/\text{s}$ .

The wavelength of water wave is $0.5\text{}\text{m}$ .

Formula used:

Write the formula for frequency.

$\text{Frequency}=\frac{\text{Speed}}{\text{Wavelength }}$

Calculation:

Substitute $0.5\text{}\text{m}$ for wavelength and $4\text{m}/\text{s}$ for speed of water wave in the formula.

$\begin{array}{c}\text{Frequency}=\frac{4\text{m}/\text{s}}{0.5\text{m}}\\ =8\text{hertz}\end{array}$

Conclusion:

Thus, the frequency of water wave is $8\text{hertz}$ .
