  3. Longitudinal wave characteristics Standing waves - a reflection phenomena Interfere Properties Resonance Natural vibrations shows may produce may produces has may produce Sound

  4. Longitudinal wave characteristics Natural vibrations shows produces may produce Sound has Resonance Properties may may produce Interfere Standing waves - a reflection phenomena

  5. Phase, degrees or radians Amplitude Intensity Level, dB Inverse square Frequency, 20-20000 Hz Doppler effect Wavelength include changes hearing W m-2 Longitudinal wave characteristics Natural vibrations shows produces may produce Sound has Resonance Properties

  6. Inverse square Level, dB W m-2 hearing Doppler effect Intensity Amplitude Phase, degrees or radians Frequency 20-20000 Hz changes include Wavelength Longitudinal wave characteristics Natural vibrations shows produces may produce Sound has Resonance Properties

  7. Longitudinal wave characteristics Reflection Echo Reverberation Refraction FST - warm to cool air SFA - cool to warm air Diffraction Wavelength  opening Pipes Disp antinode = Pressure node Closed - Alternate harmonics only 1,3,5…. Open - All harmonics possible 1,2,3…. Strings 1st harmonic - fundamental 2nd harmonic All possible shows Sound has Properties Standing waves a reflection phenomena single multi max bending include in have can be can be in vibration modes
