Waves Flashcards
1
Q
velocity
A
v = (lambda) * f
2
Q
period
A
T = 1/f
3
Q
intensity
A
I = P/A
4
Q
As a wave spreads out from a source, it’s intensity decreases the further away from the source you go, as demonstrated by analyzing two locations
A
(I1) * (r1)2 = (I2) * (r2)2
5
Q
decibels
A
Decibels = 10log(I/Io)
6
Q
frequency of beat
A
f(beat) = f1 - f2
7
Q
angular frequency
A
w = 2pif
8
Q
Doppler effect
A
f(perceived) = f(emitted) * [v(wave) +/- v(detector)] / [v(wave) +/- v(source)]
