1. If the tension in a string is doubled, then a natural frequency will (a) increase, (b) decrease by __________. 2. If the 3rd harmonic has a frequency of 600Hz, the frequency of the fundamental is ________. 3. Two strings have the same length and tension. One string has a mass per length that is 4 times that of the other string. The fundamental frequency of the more massive string will be _______ times (a) larger, (b) smaller than that of the less massive string. 4. A musician playing a string instrument may use a finger to push a string tightly against the fingerboard of her instrument, thus shortening the length of the string. This causes the fundamental frequency to (a) increase, (b) decrease, (c) not change. 5. If you take 42.0 meters of string and ball it up and put it on a scale you measure that it weighs 18.8 grams. If you tighten a length of this same string to a tension of 8.5 Newtons, what is the wave speed for waves that would travel on this string when you plucked it
