PTG 3

[Matt Anthes-Washburn]

PTG #4:
"Suppose you changed both the length and the tension of the string at the same time. What would happen to the sound in terms of wavelength and frequency?"

TE: " The wavelength and frequency would both change."

Am I wrong or is this a confusing question? Both the tension and the string length would affect the frequency. Therefore, you could change the length and the tension without changing the frequency, as in question 3, "How would you change both the tension and the length and keep the frequency the same". So I guess the answer really should be that it would change the wavelength and likely change the frequency as well. It seems very confusing following question 3.
