Waves Physics Example 1

Follow the full solution, then compare it with the other examples linked below.

easy

A wave has a frequency of

5 \text{ Hz}

and a wavelength of

2 \text{ m}

. What is the wave speed? How far does the wave travel in

10 \text{ s}

1
Use the wave equation: $v = f\lambda = 5 \times 2 = 10 \text{ m/s}$ .
2
Distance traveled in $10 \text{ s}$ : $d = vt = 10 \times 10 = 100 \text{ m}$
3
In $10 \text{ s}$ , $50$ complete waves pass any fixed point ( $5$ per second for $10$ seconds).

Answer

v = 10 \text{ m/s}, \quad d = 100 \text{ m}

A wave is a disturbance that transfers energy without transferring matter. The wave equation

v = f\lambda

relates the three fundamental wave properties: speed, frequency, and wavelength.
