9 The four strings of a musical instrument are all made of the same material and are under the same tension, but have different thicknesses. Waves travel 1. fastest on the thickest string 2. fastest on the thinnest string 3. at the same speed on all strings 4. not enough information given to decide Q15.5

11 While a guitar string is vibrating, you gently touch the midpoint of the string to ensure that the string does not vibrate at that point. The lowest-frequency standing wave that could be present on the string 1. vibrates at the fundamental frequency 2. vibrates at twice the fundamental frequency 3. vibrates at three times the fundamental frequency 4. vibrates at four times the fundamental frequency 5. not enough information given to decide Q15.6
