Unformatted text preview: 3. Resonant mode: (normal mode) most symmetrical standing wave modes 1. sinusoidal in nature 4. end conditions (bound conditions) 1. nodenode 2. antinodeantinode 3. nodeantinode 5. fraction * wavelength = Length 6. Approach 1. draw a sketch of the mode 2. determine the wavelength from the sketch 3. determine the f from (f) = v where v = v prop for a traveling wave in the same system 7. Multiple Waves 1. add the wavelengths if they come to the same point (y total = y1 + y2) 1. y1 = A1sin(kx t) y2 = A2sin(kx t + ) 2. destructive interference ( = ): waves are opposite wavelengths 3. constructive interference ( = 0): waves are exactly the same and doubles the wave III. Beats 1. f beat = abs(f1  f2)...
