Standing waves are produced on the strings of a guitar. The following represent possible comparisons of the fundamental frequency and the fundamental wavelength of the waves when a change is made. Frequency (A) Lower (B) Lower (C) Stays the same (D) Higher (E) Higher Wavelength Longer Stays the same Shorter Shorter Stays the same For each of the following situations, indicate how the second standing wave compares to the first standing wave. 20. The guitarist first plucks a thin string and then a thick string, where both strings are the same length and under the same tension. 21. The guitarist plucks a string, then tightens it and plucks it again.
