Decide whether each of the following statements are T-True, or F-False. (If the first is T and the rest are F, enter TFFFF)
A) If you decrease the tension in a string, the frequency of its fundamental vibration will get lower
B) If you have a standing wave with frequency 5 times the fundamental, there are 4 internal nodes (not counting nodes at the end of the string)
C) If the fundamental vibration of a string has wavelength lambda, then the next higher mode will have wavelength 2*lambda
D) If an ideal string can vibrate in a pure standing wave with frequency f, then (with no changes in length, tension, or material) it can also be made to vibrate in a pure standing wave with frequency of 3f
E) If an ideal string can vibrate in a pure standing wave with fundamental frequency f, then (with no changes in length, tension, or material) it can also be made to vibrate in a pure standing wave with frequency of f/2
