Standing Waves Lab Report

Physics 1408 Section E1 Standing Waves in a Vibrating fit Callie K quitner in crime: Miguel E involution Performed: March 20, 2012 TA: Raziyeh Y Abstract This lab had ii purposes. The first base was to determine the relationship in the thick of the length of a stretched telegram and the frequencies at which vibrancy occurs. The southward was to study the relationship between the absolute oftenness of oscillation and the sift and one-dimensional dope absorption of the wire. In the first part we shew the resonance, frequency and wavelength of a wire and used this data to calculate the speed of the travelling waves. For first likable, our wavelength was 1.200 m, lay out by the formula ?=2L/n. In the second part we used tensity and velocity to find muckle slow-wittedness. For the first notch, with a accent of 10.3 N, the velocity was 86 m/s with a boilers suit mass density of 0.018. Discussion In the lab we precious to find the frequency at which resonance occurs on a stretched wire as well as look at the relationship between the frequency of vibration and tension and linear mass density of the wire. For the first procedure, we increase the frequency until we found resonance, and recorded frequencies and nodes to calculate wavelength.

We did this for first large-hearted through stern harmonic, and then found the velocities victimisation our measurements. In the first harmonic phase, our signal generated frequency was 36±1 Hz, wire frequency was 72 Hz, the number of nodes was 2 and the wavelength was 1.200 m. This was found by victimisation the equation ?=2L/n. For the second procedure, using a wire of a certain linear ma ss density we found the frequency of the wir! e as it oscillated in its perfect mode, or net resonance mode, as we increased the tension by pathetic the hanging mass to a higher(prenominal) notch. We performed this procedure again using a wire with a different linear mass density.If you want to get a full essay, order it on our website: OrderEssay.net
