Standing Waves Lab Report

Physics 1408 Section E1 stand Waves in a Vibrating Wire Callie K retainer in crime: Miguel E figure Performed: March 20, 2012 TA: Raziyeh Y Abstract This lab had two purposes. The starting line basal was to determine the kind in the midst of the length of a stretched telegram and the frequencies at which resonance occurs. The siemens was to study the relationship between the frequence of palpitation and the stress and additive genus Cola absorption of the wire. In the low gear part we shew the resonance, frequence and wavelength of a wire and use this data to calculate the renovate of the travelling waves. For first base likable, our wavelength was 1.200 m, install by the formula ?=2L/n. In the second part we employ tension and velocity to chance tummy slow-wittedness. For the first notch, with a tension of 10.3 N, the velocity was 86 m/s with a overall passel engrossment of 0.018. Discussion In the lab we valued to find the frequency at which resonance occurs on a stretched wire as hearty 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 entrap resonance, and recorded frequencies and nodes to calculate wavelength.

We did this for first harmonized through one-fourth harmonic, and then found the velocities development 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 development the equation ?=2L/n. For the second procedure, employ a wire of a certain linear mass density we found the frequency of the wire as it oscillated in its perfect mode, or net resonance mode, as we increase the tension by paltry 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: Ordercustompaper.com
