The second harmonic, also called the 1 st overtone, is an integer (whole number) multiple of the fundamental frequency. The fundamental frequency is the frequency of one period of a wavelength. Simply put, this means that one period of the wave goes to the bottom of the cylinder and back in the same amount of time it takes for the tuning fork to vibrate one time. The change in sound in the water column will occur when the graduated cylinder produces the same resonance as the tuning fork. If it is warmer, the speed will be faster. Compare your experimental value to the true value. The speed of sound in air is 343 m/s (nearly a mile in 5 seconds!) at 20☌.
H is the height distance between the top of the water and the lip of the cylinderĭ is the diameter of the water container in meters Calculate the velocity of sound at this height using the following equation:į is the frequency of the tuning fork in Hz.Remove some water and experiment with adding it again until you can identify the height of the water at which the frequency jumps.Listen for the point when there is a change in pitch (frequency). If you cannot do it yourself, ask a friend or family member to help you. While keeping the tuning fork over the opening of the container, slowly pour more water into the cylinder.Please select apply now below to create an account and to complete the application.
