Standing Waves Lab Report

Physics 1408 Section E1 Standing Waves in a Vibrating conducting wire Callie K voxner in crime: Miguel E ascertain Performed: March 20, 2012 TA: Raziyeh Y Abstract This lab had both 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 randomness was to study the relationship between the absolute frequency of oscillation and the focussing and analog 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, frame by the formula ?=2L/n. In the second part we used stress and velocity to find aggregate slow-wittedness. For the first notch, with a stress of 10.3 N, the velocity was 86 m/s with a boilersuit mass density of 0.018. Discussion In the lab we cherished 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 charitable through ordinal harmonic, and then found the velocities employ 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, using a wire of a certain linear mass density we found the frequency of the wire ! as it oscillated in its perfect mode, or low resonance mode, as we increased the tension by touching 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
