 doppler formula
Definition
 f new = f old (v +/- vo)                    (v +/- vs)   "v" can equal sound (330) or light (3 x 108)
Term
 Snell's Law
Definition
 n1 sin q1 = n2 sin q2
Term
 Critical angle
Definition
 q critical = sin -1 (n little/n big)
Term
 double slits
Definition
 l = dsin q     n   l = xd       nL
Term
 single slits
Definition
 λ = W sinq    n   λ = Wy       nL
Term

Term
 laws of strings   length diameter density tension
Definition
 frequency indirectly proportional to length, diameter, density 1/2   f1 l1 = f2 l2 f1 d1 = f2 d2 f1√D1 = f2 √D2   frequency directly proportion to tension 1/2   f1 √T2 = f2 √T1
Term
 area for sound waves
Definition
 Surface area of a sphere   4pr2
Term
 wavelength in tubes   open   closed
Definition
 open tube      l = 2l   closed tube     l = 4l   l = lenght of tube
Term
 harmonics   nodes antinodes wavelength frequency velocity
Definition
 nodes destructive interference = n + 1   antinodes constructive interference = n   l = 2/n (l)   f = n x fo   velocity is a constant = 2lfo   n = # of harmonic     l = length of string
Term
