In this video, we learn about the different properties of sound waves and how they affect the quality of sound. We also learn about how sound waves travel and how they are affected by different objects and surfaces. Finally, we explore the effects of amplitude on sound waves.

  • 00:00:00 In this video, the properties of sound are explained, including its vibration, which has a regular movement. There is a connection between sound and vibration that we can observe by suspending a metal bridge between two posts. If we hit one end of the bridge with an energy impulse, the length of the impulse travels through the whole length of the bridge, compressing the rings of the bridge. We then observe that the rings of the bridge do not move only along the impulse's path, but also the air around the bridge moves with the impulse. This is similar to what happens with sound waves in the air. Next, the properties of various sounds are examined by making a series of experiments. First, water is used to create waves on a glass surface by vibrating a small motor. The waves created are easier to see than the sound waves, and their distance between waves is regular. This distance is called the wave length, and is measured from the crest of one wave to the crest of the next. Different sounds have different wave lengths, and this is used to determine their distance from us. Finally, by following several sound waves simultaneously, we can determine if a storm is approaching or retreating. Besides wave length, sound also has other properties, such as
  • 00:05:00 In this video, we learn about the properties of sound waves, including their wavelengths and frequency. We also learn about how sound waves are affected by objects and surfaces, and how they travel. Finally, we explore the effects of amplitude on sound waves.
  • 00:10:00 This video discusses the acoustic properties of sound, including amplitude, frequency, and phase. It explains how these properties impact the sound produced by an instrument, and how a sound technician can improve the quality of an audio recording by changing acoustic properties of a room. Finally, the video describes how acoustic properties of the mother's body can be used to determine the health of the baby before birth.
