Unformatted text preview: B. The wavelength is unchanged but the wave speed doubles. C. Both wavelength and wave speed are unchanged. C Correct As you have discovered, when waves travel along a string, the wave speed remains unchanged, unless the properties of the string are changed. The wavelength can be varied only by changing the frequency, or alternatively the period, of the oscillator that creates the waves....

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
