WebSound waves radiate in all directions away from the source like ripples on the surface of a pond. The compressions and decompressions associated with sound waves are detected as changes in pressure by the structures in our ears and most man-made sound receptors such as a hydrophone, or underwater microphone. The basic components of a sound … WebSound waves are longitudinal or compression waves that transmit sound energy from the source of the sound to an observer. Sound waves are typically drawn as transverse waves, with the peaks and troughs representing the areas of compression and decompression of the air. crystal and jesse adopted russian girl

WebActually, that is an oversimplification, the wave's velocity depends on the medium through which it is moving: * Radio waves and light move at the speed of light... * sound is a wave traveling through the air. The actual speed depends on temperature, humidity, and altitude... * waves on the ocean are dependent on the depth of the ocean floor... WebSep 2, 2024 · A sine wave is the most basic sound we can produce. The length of the cycle is between points A and B. Frequency is a measurement of sound in cycles per second, or Hertz (Hz). If a sound has a frequency of 20Hz, an extremely low frequency, it is cycling 20 times a second. WebSep 10, 2024 · There is a complete explanation there. Likewise, when an ambulance passes by and you hear the doppler effect, that is because the sound waves are compressed as they come toward you, and expanded as they move away. That gives a complete explanation of why the sound changes as the ambulance passes by. crystal and jesse
