Waves

1. Longitudinal (S)

   • Sound Waves
     • Moves fastest in (s), slowest in (g)
       • How to Calculate V-sound in (g)
       • How to Calculate V-sound in (l)
       • How to Calculate V-sound in (s)
     • V-sound
       • Directly proportional to IMF strength
         • Ranked by increasing IMF strength: S>L>G
       • Inversely proportional to MW
     • ↑ A --> ↑ Volume
       • Subjective but measurable
         • Measured as intensity I (W/m^2)
     • ↑ f --> ↑ Pitch
       • High pitch = high frequency & VICE VERSA
     • Doppler Effect
   • Springs/Slinkies
   • Characterized by condensation and rarefaction
     • Condensation = Low V, high P and density
     • Rarefaction = High V, low P and density

2. Transverse (S)

   • Radio waves
   • Light waves
   • Microwaves

3. Periodic waves characterized by several features

   • Amplitude (A)
   • Cycles
     • Crest-Creast Trough-Trough
   • Period (T)
     • Inverse of f
     • # sec/cycle
   • Frequency (f)
     • # Cycles/sec (Hz)
   • V-sound = f*λ
   • Wavelength λ
     • Length of one cycle
