Abstract:
This experiment was conducted to find out how the resonant frequency generated by a tuning fork will change at different temperatures.
 
Procedure preview:
1. For this experiment, the independent variable is the temperature of the tuning fork. The dependent variable is the resonant frequency of the tuning fork. This is determined by measuring the frequency with a frequency sensor and scope. The constants (control variables) are the resonant frequency of the tuning fork, the material of the tuning fork and the dimensions of the tuning fork.2. The tuning fork temperature will be varied at 0°C, 25°C, 50°C, 75°C and 100°C.3. The tuning fork is kept overnight in the freezer of the refrigerator so that its temperature will be 0°C. The next day, the .....
