A mandolin is a stringed instrument that consists of 4 pairs of identical strings. Each string in a given pair should be at the same tension as its mate and so should produce the same fundamental frequency. Often such strings may be tuned relative to each other by listening for the beat. As you adjust the tension on one of the strings and you feel the beat frequency, you know that the strings are
closer to being tuned to the same frequency under which of these conditions?
1.The beat frequency gets larger and larger as you adjust the tension.
2.The beat frequency remains constant as you adjust the tension.
3.The beat frequency gets lower and lower as you adjust the tension.
4.It is not possible to tune the strings to the same fundamental frequency by using the beat frequency that exists between them.
