The resonating frequency of an object describes how many times the object moves from one extreme position on a spring to the next in a given unit of time. Different objects have different resonating frequencies. The resonating frequency also relies on the spring being used. To find the resonating frequency of an object, you will need basic familiarity with using mathematical formulas and will need to know the basic properties of the apparatus with which you are measuring resonating frequency.
Instructions
1. Weigh the object of choice. Record the weight and label it "m1."
2. Weigh another object of different weight. Record this weight as "m."
3. Attach the spring to a solid surface from below, so that the spring hangs downward.
4. Attach the object of interest to one end of the spring. Measure how far it pulls the spring down from its original position. Record this distance as "d1."
5. Replace the object of interest with the object of differing weight. Repeat the previous step. Record the distance as "d2."
6. Compute the number given by the formula (m1-m2)/(d1-d2). Call this number "k."
7. Compute the resonating frequency using the following formula:
Divide k by m.
Take the square root of the result.
Divide this result by 2pi, where pi is equal to 3.14159
