Experiment 12

Summary For this lab my partners and I were asked to defecate stand up waves and mould the oftenness of the waves. First we examined the weight and space of the absorb. We therefore link up the pull out to a string vibrator and hung a certain view at the end of the string to produce a stand wave with one node. We whence added weight to create up to 6 remindful nodes. later this, for the next try out we were asked to regain the wave aloofnesss ? of each resounding node. The formula for wavelength is ?=C/v. We past compared (? vs. ?FT). We then found the slope, y-intercept, and cor notification coefficient coefficient. After finding these things we then were asked to count on % actus reus between the observational frequency and the known frequency. My partners and I then computed tension and voltaic pile needed to produce the ball carrier printing smelling(p) mode. Lastly we used the analog relation to determine the push-down storage neede d to produce the tenth aromatic mode. Conclusion From this experiment I learned a striation about standing waves. This experiment allowed me to visualize the waves and the resonant nodes. The length of the string was 1.08m and the galvanic pile of the string was .000316kg.

The mass needed to advance one resonant node was .15kg, two resonant nodes was .0075kg, troika resonant nodes was .04kg, foursome resonant nodes was .015kg, and five resonant nodes was .01kg. The slope of the graph was .7738 m?n, the y-intercept was .1014m, and the correlation coefficient was .9783. From the plot we were able to det ermine that the plot is linear. The experi! mental frequency of the string vibrator was 72.70 1/s. The % faulting was 17.4% The tension and mass needed to produce the first resonant mode was 7.79N and the linear relation used to determine the mass needed to produce the tenth resonant mode .0779NIf you postulate to get a full essay, order it on our website: OrderCustomPaper.com
