| | Abstract | This project explores the behavior of air when influenced by specific |
| | sound waves. The purpose of my experiment is to test the variation of |
| | energy of a torridal ring when the frequency of the sound wave that |
| | produces it is changed; and to test whether a torridal ring will be formed |
| | when the amplitude of the sound wave that produces it will be changed. |
| | |
| | For this experiment, I am going to produce a ring of air, which will be |
| | visible to the naked eye as there will be tiny smoke particles in it. This |
| | smoke ring is made by attaching a speaker to the top of the cup. Next, a |
| | circular hole is cut in the bottom of the cup about 4/10 the radius of the |
| | bottom of the cup. Now when a saw tooth tone is played through the |
| | speaker, and the cup is filled with smoke, a ring of smoke will be |
| | produced. |
| | By changing the frequency and amplitude of this sound wave, I will see |
| | how the energy of the smoke ring is affected. The energy will be |
| | measured by seeing at how far a cotton ball, which is attached to a string |
| | and the string that is attached to the underside of table, will move in term |
| | of degrees when different frequencies and amplitudes are played. |
