Wave question

  1. Apr 24, 2006 #1
    For this wave assume the amplitude is .02 m and the velocity is
    5 m/s.

    a) Draw a graph of a wave with a speed twice the original and a frequency double the original.

    Ok, so in the original the speed is 5m/s, and wavelength = .25m
    Using the equation f= v/wavelength we get that f= 20Hz
    Now for the new graph the speed is 20 m/s and the frequency is 40Hz, thus the wavelength is the same, .25m.
    So for this new graph, would it just be the same as the original graph?

    I think so, with a different "v" vector value at the bottom of the picture.
