To redo the experiment, click on the ‘Reset’ button.Click on the ‘Show result’ button to see the result.Click on the zoom in icon to view the zoomed area.Drag the inner tube/Change the slider to adjust the height of the air column.Click on the ‘Sound On’ button to hear the sound.Click on the ‘Hit tuning fork’ button to start/stop vibration.Select the frequency of the tuning fork using the slider. Select the diameter of the tube using the slider.Select the surrounding temperature using the slider.Select the surrounding from the drop down list.It is given by f n/2L (T/), where f is the frequency, n is the number of prongs on the tuning fork, L is the length of the prongs, T is the tension in the prongs, and is the density of the material the fork is made of. Simulator Procedure (as performed through the Online Labs) The tuning fork frequency equation is a mathematical formula used to calculate the frequency of a tuning fork. V - velocity of sound in air at temperature t. Where, v 0 - velocity of sound in air at 0 0C. By using the value of v, we can calculate the velocity of sound in air at 00C as,.The mean of the calculated values will give the velocity of sound in air at room temperature.Repeat the experiment with tuning forks of different frequencies and in each time, calculate the value of v.We can now calculate the velocity of sound in air at room temperature by using the relation,.This is taken as the second resonant length, l 2. Measure the length of air column at that position.Change the height of the tube until the maximum sound is heard.Excite the tuning fork again and place it on the mouth of the tube.Then raise the tube approximately about three times the first resonant length.This is taken as the first resonant length, l 1. Now, raise the tube and the tuning fork until a maximum sound is heard.Sound waves are passes down to the tube and reflect back at the water surface. Place the vibrating tuning fork horizontally above the tube.The tuning fork now produces longitudinal waves with a frequency equal to the natural frequency of the tuning fork. Take a tuning fork of known frequency and striking it with a rubber hammer.The inner tube of the resonance column is lowered to minimum so that the length of air column inside the tube is very small.Can you explain this answer? tests, examples and also practice Physics tests.
