Finding period and speed of a 19 Hz wave

[mortho]

Homework Statement

A wave traveling in the positive x direction with a frequency of 19.0 Hz

The full amplitude of the wave is 0.18 m and the wavelength is 0.20 m

What is the period and speed of the wave?

Homework Equations

speed=(frequency)*(wavelength)
Frequency=1/period

The Attempt at a Solution

I figured the speed by doing 19*0.20 which equaled to 3.8 m/s
For the period, i just did 1/19 and got 0.0526 s but am not too sure about this answer. Please direct me! Thanks!

Your answer is right. 1/19 would be the Period.
