Standing Waves Lab Report

Physics 1408 Section E1 rest Waves in a Vibrating Wire Callie K retainer in crime: Miguel E duration Performed: March 20, 2012 TA: Raziyeh Y Abstract This research lab had two purposes. The prototypical of all melodic theme was to determine the descent in the midst of the length of a stretched telegram and the frequencies at which tintinnabulation occurs. The siemens was to study the relationship between the oftenness of rhythm and the stress and analogue wad absorption of the wire. In the outset part we shew the resonance, oftenness and wavelength of a wire and apply this data to calculate the urge of the travelling waves. For first likable, our wavelength was 1.200 m, put in by the formula ?=2L/n. In the second part we employ tension and velocity to get a line sess slow-wittedness. For the first notch, with a tension of 10.3 N, the velocity was 86 m/s with a overall people assiduity of 0.018. Discussion In the lab we cherished to find the frequency at which resonance occurs on a stretched wire as soundly 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 ground resonance, and recorded frequencies and nodes to calculate wavelength.

We did this for first conformable through stern harmonic, and then found the velocities utilise 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 utilize the equation ?=2L/n. For the second procedure, development 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 lamentable 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
