Term
Doppler Effect
 Definition
F'=Fo (V+Vo / V-Vo)
Vo= (+ Vo) when traveling TOWARDS source
Vo= (- Vo) when traveling AWAY from source
opposite is true for Vs (-) toward (+) away
Term
Sinusoidal Wave
 Definition
y= Asin(kx-wt + delta)
Term
Velocity (v)
 Definition
Velocity(v) = lambda / period = (lambda)(frequency)
Term
Wave number (K)
 Definition
k = 2pi / lambda
Term
Angular Velocity (w)
 Definition
w= 2pi/T = 2pif
Term
Tension (T)
 Definition
T=mg
Term
Mass Per unit Length mew (u)
 Definition
u= m / l
Term
Wave Speed (V)
 Definition
V= sqrt(t/u)
