Sound waves can travel through air, solids, and liquids. Particles of the fluid (i.e., air) vibrate back and forth in the direction that the sound wave is moving. Reading Question 16.5. This is a great classic experiment that’s been around as long as I can remember. off the vibration or letting the string go limp, the sound will usually travel well. D) amplitude. …, Question: What are the steps in focusing on a microscope? How do Sound Waves Travel? They continue to travel through the string, as long as it is held taut, to the receiving cup. Sound is vibrations, small waves of pressure in the air e.g. Since sound waves travel more quickly through solids, we hear the sound more clearly. Sound is basically the movement of the air vibrating from the sound produced by something making a noise. Just like a string of an instrument, vocal chords vibrate, letting sound waves resonate. A: If you have a modern digital phone, the answer is very complicated. When the string is pulled taut and someone speaks into one of the cans, its bottom acts as a diaphragm, converting the sound waves into longitudinal mechanical vibrations which vary the tension of the string. Since sound waves travel more quickly through solids, we hear the sound more clearly. The vibrations, or sound waves, move up the string and allow your ears to hear it. More fun with this project! When the can’s string is stretched tightly, it gives the sound wave vibrations a straight path to travel down, so the sound is carried stronger through the string and directly into the other person’s ear. Sound waves travel through air in a similar way. The sound can travel in air when: (a) Particles of medium travel from one […] C. Sound and water waves. This elementary sound science project shows kids how sound waves can travel through a string and be converted back to audible sound at the opposite end.
