1. Virtual Lab

2. To begin… Read the entire lab sheet before continuing with this virtual lab so that you will be familiar with the procedures used. The following slides take you step-by-step through the procedure. You will need to make your own data table for this lab. Be sure to use a ruler to make straight lines and to record all data requested.

3. Below is the graduated cylinder with water and the resonance tube.

4. The air temperature is shown below.

5. The frequency of the tuning fork is shown below in Hz.

6. Watch the video at the following link to see the first trial. http://www.youtube.com/watch?v= BObALr_CuhQ&feature=youtu.be

7. The distance above the water is shown in the diagrams below. The top of the tube is at 50 cm and you can see where the level of the water is in the closeup in the picture on the right. Remember, you are recording the distance from the water to the TOP of the tube.

8. The diameter of the tube is shown to the left.

9. Perform the calculations as described.

10. You will not need to perform a second trial for the same tuning fork, but you will need to do the experiment again for another tuning fork with a known frequency and for a third tuning fork with an unknown frequency. The data for these two new tuning forks are shown in the following slides

11. Watch the video at the following link to see the second tuning fork. http://www.youtube.com/watch?v =UuvRAKitPmQ&feature=youtu. be (Data is continued on next slide.)

12. The results are shown below.

13. Watch the video at the following link to see the second tuning fork. http://www.youtube.com/watch?v= vbI-G1LEUXE&feature=youtu.be (Data is continued on next slide.) Frequency is unknown.

14. The results are shown below.

15. Watch the following video for the experiment with the tuning fork shown below and cold water. This is the same tuning fork you used in the first trial. http://www.youtube.com/watch?v=LT3FmHZW Si0&feature=youtu.be http://www.youtube.com/watch?v=LT3FmHZW Si0&feature=youtu.be

16. The result is shown below.

17. Watch the video below for the 512 Hz tuning fork when played loudly. http://www.youtube. com/watch?v=bkc2nn 2hW1c&feature=yout u.be http://www.youtube. com/watch?v=bkc2nn 2hW1c&feature=yout u.be Watch the video below for the 512 Hz tuning fork when played softly. http://www.youtube. com/watch?v=YiCRm C6JKpM&feature=yo utu.be http://www.youtube. com/watch?v=YiCRm C6JKpM&feature=yo utu.be

18. The result of the loud test is shown below. The result of the soft test is shown below.

19. Thats It!!! Be sure that your data table is complete. Finish the calculations and conclusion questions on your own and turn in your lab by the date your teacher specified. Good luck! If you need any help, be sure to ask your teacher.
