Name ___________________________________________ Date ________________ Period _________ PHYSICS PART I – SURFING THE WAVES Wave Theory Waves transfer ________ through a medium. The __________ doesn’t move – the energy does. Wave Types Longitudinal Wave Molecules move _________________________ as the wave. Transverse Wave Molecules move ________________to the direction of the wave.
Actual Wave How we can think of it Amplitude = Wavelength – Pitch velocity = wavelength x frequency v = λ ƒ Velocity is constant As frequency increases, _____________________________. As wavelength increases, ____________________________.
Interference Standing Wave In a closed tube, the wave _________________________. Overtones Waves of a ________ frequency than the fundamental – add richness to tones. Different instruments accentuate different ____________.
Loudness Measured in __________ – indicate the amplitude of the wave. The Human Ear
