  1. Waves and Sound: 77
    Transverse wave particles vibrate perpendicular to the wave direaction and longitudinal wave particles vibrate parallel to the direction of the wave propagation.
  2. Waves and Sound: 78
    Sound waves are mechanical longitudinal waves. Light waves are electromagnetic transverse waves.
  3. Waves and Sound: 79
    The speed of a wavedepends only on the properties of the medium.
  4. Waves and Sound: 80
    The energy of a wave is directly proportional to the square of the amplitude.
  5. Waves and Sound: 81
    The intensity of sound is inversely proportional to the distance.
  6. Waves and Sound: 82
    Superposition Principle: When two or more waves exist simultaneously in the same medium, the resultant amplitude at any point is the algebraic sum of the amplitudes of each wave.
  7. Waves and Sound: 83
    The harmonics produced in open pipes are similar to those produced in strings. The fundamental occurs when the lenght of the pipe (or string) equals 1/2 λ.
  8. Waves and Sound: 84
    The fundamental on a closed pipe occurs when the length of the pipe equals 1/4λ. Only the odd harmonics are possible for a closed pipe.
  9. Waves and Sound: 85
    Whenever two waves exist simultaneously in the same medium and they are nearly at the same frequency, beats are set up.
  10. Waves and Sound: 86
    Doppler effect is the apparent change in frequency of a source of sound when there is relative motion of the source and the listener.
