Question

a longitudinal wave travels:
only along the earths longitudinal lines.
perpendicular to a latitude wave.
perpendicular to the direction of oscillations.
in the same direction as the oscillations.

an ocean wave has a frequency of 2 hz and a speed of 20 m/sec. what is the wavelength of this wave?
select one:
0.1 meter
10 meters
20 meters
40 meters

Explanation:

Step1: Recall the formula for wave speed

The formula for wave speed \(v\) is \(v = f\lambda\), where \(v\) is the speed of the wave, \(f\) is the frequency, and \(\lambda\) is the wavelength.

Step2: Rearrange the formula to solve for wavelength

We can rearrange \(v = f\lambda\) to \(\lambda=\frac{v}{f}\).

Step3: Substitute the given values

Given \(v = 20\space m/s\) and \(f=2\space Hz\), substitute into \(\lambda=\frac{v}{f}\). So \(\lambda=\frac{20}{2}\).

Answer:

10 meters
