The apparatus consisted of a formative tube filled with water linked to a water container. Thiscontainer could be displaced vertic totallyy in order to change the water take. We would thenmake a correct fork vibrate above the pipe and change the water level until the resonance wasat maximum intensity. Hypothesis The pep pill of sound is 330 ms -1 , the relationship between velocity, frequencyand wave outperform is represented by the construction v= ? , 1) Raw information presented skirt 1 Table 1 shows the frequency of the different tune forks and the length of air needed for maximum resonance. The geological fault on the length was estimated to 0. 1 cm as we repeated eachexperiment several times. Note the error on the forks frequencies is a mere estimation as theyare accurately fine-tune during manufacture.

The distance measured represents ? of the completestanding wave therefore ? = measured length * 4-From the general formula v= , we find that velocity of sound in ms -1 for the commencement exercise tune upfork experimented is v = 512 ? 0. 157 ? 4 = 321. 536-Calculating the error for velocity ? v = ( / ? + / ? ) ? vFor the first tuning fork ? v = (0. 001 / 0. 157+0. 1/512) ? 321. 536 ? v = 2. 1108 ms -1 ? v ? 2 ms -1 ? v ? 322 +/- 2 ms -1 To find the mean velocity we subjoin all values of v and divide the sum by the number of values. A similar process was completed for the mean ? v. Results of all processed data are shown in table 2 Table 2 Frequency Hz -1 Length m -1 Velocity ms -1 ? velocity +/- ms -1 512. 00. 1573222480. 00. 1693242456. 10. 1783252426. 60. 1923282406. 40. 2023282384. 00. 2153302362. 00. 2263271341. 30. 2433321320. 00. 2603331304. 40. 2703291288. 00. 2883321271. 20. 3083341256. 00. 3233311error +/- 0. 1error +/- 0. 001 Mean velocity = (322+324+325+328) / 13 ? 329Mean ? v = (2+2+2+2+2+2+1+1+1)/13 ? +/- 2 ms -1 As v = , and ? = v / ? , let be constant of 330 ms -1 then ? ? 1/ ? By plotting the represent of Frequency over 1/ ? we obtain a straight line. The slope of thisline represents the constant v and the y-intercept a systematic error.
