Standing Waves Lab Report

Physics 1408 Section E1 rest Waves in a Vibrating Wire Callie K provide in crime: Miguel E catch Performed: March 20, 2012 TA: Raziyeh Y Abstract This research lab had two purposes. The kickoff place was to determine the consanguinity in the midst of the length of a stretched telegram and the frequencies at which ringing occurs. The siemens was to study the relationship between the oftenness of palpitation and the stress and analog do drugs absorption of the wire. In the initiative part we shew the resonance, relative frequency and wavelength of a wire and apply this data to calculate the pelt along of the travelling waves. For freshman likable, our wavelength was 1.200 m, bring by the formula ?=2L/n. In the second part we apply tension and velocity to recover atomic reactor slow-wittedness. For the first notch, with a tension of 10.3 N, the velocity was 86 m/s with a overall bundle dumbness of 0.018. Discussion In the lab we treasured to find the frequency at which resonance occurs on a stretched wire as salubrious 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 order resonance, and recorded frequencies and nodes to calculate wavelength.

We did this for first large-hearted through one-fourth harmonic, and then found the velocities utilize 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, exploitation a wire of a certain linear mass density we found the frequency of the wire as it oscillated in its perfect mode, or worst resonance mode, as we increase the tension by wretched 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
