The velocity of sound by means of resonance

University of Salahaddin Hawler nurture College Physics Dept. Shaqlawa Name of try The velocity of give-up the ghost by promoter of sonority electron tube closed at one end. No. experiment 5 Name Goran Kamaran A. razaq Stage 1st Class Group C Date 12/12/2013 Apparatuses- This lab utilizes the following materials Resonance tube Pail of water Tuning forks Rubber mallet Measuring enrol Thermometer Thorey- Fill the tube with water to about 10cm to the open end of the tube. To change the aim of the water in the tube. move the berth bucket up and down in the vertical irection.Use five different tuning forks and the earmark head of the mallet. Strike the tuning fork with the appropriate mallet above the open end of the tube and slowly start lowering the side bucket so the water level goes down until you hear an cast up In sound which Is called reverberance. Record the location where the resonance occurred and record the height. afterwards you get the first resonance, repeat by lowering the water elevate down the tube until you get a total of two resonance recordings. Repeat the experiment with a different tuning fork and record the ppropriate data.Each fork was struck above the water level and the water level was slowly moved down until a resonance was heard. The distance where the resonance occurs were recorded and the speed of the waves were determined. The experimental speed of sound was then compared to the cipher theoretical speed of sound. The results obtained were very close to the theoretical speed of sound thus proving that they were precise. Ill. The cause of errors in the process. 1- the rooms noise 2- Before now, we go forth not work in scientific laboratories. Mistake ratio OR Error ratio Error = I . 05
