1. Period variable
T
2. Frequency variable
f
3. Amplitude variable
A
4. Wavelength variable
λ
5. Wavelength definition
the distance between any two successive parts of a wave
6. Amplitude definition
the magnitude of the maximum displacement, or the maximum distance, from the particles equilibrium position
7. Frequency definition
the number of waves per second that pass by a given point during each second
8. Frequency formula
f=1/T
9. Period definition
the time for one complete wavelength to pass by a given point
10. Wave Speed formula
v=λf
11. Transverse wave:
the disturbance occurs perpendicular to the direction of travel of the wave. Example: wave on a stretched string
12. Longitudinal wave:
the disturbance occurs parallel to the direction of travel of the wave. Example: sound
13. Frequency range of the human ear:
20 Hz to 20 kHz
14. Principle of Superposition
At any time, the combined waveform of two or more interfering waves is given by the sum of the displacements of the individual waves at each point in the medium
15. Tube open at both ends:
has displaced antinodes at both ends.

L=n(1/2λn)
16. Tube open at one end:
• has displaced antinode at the open end
• has displaced node at closed end

L=m(1/4λm)
17. Tube open at both ends:

Fn=

n=
Fn= V/λn = n(v/2L) = nf1

n= 1,2,3,...
18. Tube open on one end:

Fm =

m=
Fm = V/λm = m(V/4L) = mf1

m= 1,3,5,...
19. Intensity =
Loudness
20. Frequency =
Pitch
21. Harmonics =
Quality
22. β =
10 log (I/I0)
23. I0 =
10-12 w/m2
24. Doppler Effect Formula

o=
s=
v=
Fo = ((V±V0) / V∓V0)) fs

• o= observer
• s=source
• v=speed of sound
25. Doppler Effect: towards
top signs
26. Doppler Effect: away
bottom signs
