The apparatus consisted of a plastic tube filled with piddle linked to a water container. Thiscontainer could be displaced vertic anyy in order to change the water level. We would thenmake a tuning fork beatify above the pipe and change the water level until the resonance wasat uttermost intensity. Hypothesis The velocity of sound is 330 ms -1 , the relationship between velocity, frequencyand wavelength is represented by the formula v= ? , 1) Raw data presented display panel 1 Table 1 shows the frequency of the different tuning forks and the length of air needed for maximum resonance. The misapprehension 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 calibrated d uring manufacture.

The distance measured represents ? of the completestanding wave therefore ? = measured length * 4-From the general formula v= , we baring that velocity of sound in ms -1 for the first tuningfork 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 gibe all values of v and divide the sum by the number of values. A similar process was completed for the mean ? v.

By plotting the graph of Frequency over 1/ ? we obtain a straight line. The gradient of thisline represents the constant v and the y-intercept a systematic error. The situation is illustrated by graph 1 Graph 1 y = 313. 24x + 16. 736200. 0250. 0300. 0350. 0400. 0450. 0500. 0550. 00. 55 0. 75 0. 95 1. 15 1. 35 1. 55 1. 75 1/wavelength m-1 Note that if we add the y-intercept to the gradient we obtain the value of 329. 976 ms -1 for thespeed of sound.
