For this lab my partners and I were asked to defecate stand up waves and mould the oftenness of the waves. First we determined the weight and length of the string. We therefore link up the string to a string vibrator and hung a certain view at the end of the string to produce a stand wave with one node. We then added weight to create up to 6 remindful nodes. After this, for the next try out we were asked to regain the wavelengths ? of each resonant node. The formula for wavelength is ?=C/v. We then compared (? vs. ?FT). We then found the slope, y-intercept, and correlation coefficient. After finding these things we then were asked to count on %error between the observational frequency and the known frequency. My partners and I then computed tension and voltaic pile needed to produce the offset printing resonant mode. Lastly we used the analog relation to determine the push-down storage needed to produce the tenth resonant mode.
Conclusion
From this experiment I learned a lot 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 mass of the string was .000316kg.
The mass needed to make one resonant node was .15kg, two resonant nodes was .0075kg, three 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 determine that the plot is linear. The experimental frequency of the string vibrator was 72.70 1/s. The %error 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 want to get a full essay, order it on our website: Orderessay
