Experiment Name: Speed of sound Purpose of experiment: measurement the speed of sound from the sound waves set up in the closed resonance tube. Apparatus: 1- Closed resonance tube of variable length (see fig (1) below). 2- Meter scale. 3- Tuning forks of different frequencies. 4- Rubber pad. 5- Thermometer. Method 1- Select the fork of highest frequency (512 Hz). 2- Strike it smartly on a rubber pad hold it over the mouth of the tube. 3- Adjust the shortest length of the resonance column until resonance occurs. 4- Measure the length of the air in the tube, L (see figure below). 5- Repeat the measurement two or three times and take the mean (LI). 6- Obtain different values of L using other forks (412 Hz......etc). 7- Measure the diameter of the tube to obtain its radius (r). As shown in figure (1): 8- Record the room temperature. 9- Write your results in the table below F (Hz) L (cm) 1/F (Le)=L+0,6 r Where L: Shortest resonance length of air column Lc: Corrected length C: Speed of sound F: Frequency F (Hz) 180 420 384 320 288 C-4FL (m\sec) Live 0-17 0.19 0.22 025 29 2-X10-9 23X10-9 26 x 10-7 31 A 10-7 34 x 154 10- plot the graph from the above obtained results for (1/F) on x-axis against (L) on y-axis and find its slope, as shown in figure (2)
