When you’re in slide show view, click the triangle to return to the game board slide. Sound waves travel faster in solids than they do in liquids than they do in gases. However, within a single phase of matter, the inertial property of density tends to be the property that has a greatest impact upon the speed of sound. A sound wave will travel faster in a less dense material than a more dense, similar material. A sound wave will travel nearly three times faster in Helium than it will in air, due to the lower mass of Helium particles as compared to air particles. 50 Category 4

When you’re in slide show view, click the triangle to return to the game board slide. Remember that sound is a vibration of kinetic energy passed from molecule to molecule. The closer the molecules are to each other and the tighter their bonds, the less time it takes for them to pass the sound to each other and the faster sound can travel. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly Higher temp = faster speed 30 Category 5

When 3 beats per second is first heard, the tuner knows he was 3 hertz off the correct frequency. But when he tightened the string and increased its frequency, a lower beat frequency would have told him he was on the right track. But the greater beat frequency told him he should have been loosen­ing the string. When there is no beat frequency, the frequencies match. 50 Category 5
