Waves Flashcards
1
Q
Wave
A
- -> oscillations/vibrations of AIR PARTICLES
- ->transfer energy
- ->no material transferred
2
Q
Longitudinal wave
A
- -> vibration
- ->PARALLEL
- -> direction of travel
–>pressure wave(compression)
3
Q
Example of longitudinal waves
A
- ->sound waves
- ->P-waves
4
Q
Transverse wave
A
- ->vibration
- ->perpendicular
- ->direction of travel
5
Q
amplitude on transverse wave
A
- ->maximum displacement
- ->OF PARTICLES
- ->from equilibrium position
6
Q
wavelength on transverse wave
A
- -> joined
- ->by two
- ->troughs
7
Q
Effect of higher amplitude
A
Louder
8
Q
Period
A
- ->Time to return to same point
- ->wave point
9
Q
rarefaction
A
spread out place
10
Q
compression
A
scrunched up place
11
Q
wavelength on longitudinal wave
A
start of compression to end of rarefraction and vice versa
12
Q
wave velocity formula
A
velocity(m/s)=frequency(Hz)x wavelength(m)
13
Q
Frequency formula
A
1/time period(T)
14
Q
When Doppler Effect Happens
A
- ->producing or reflecting waves
- -> moving
15
Q
Explain Doppler Effect
A
- ->wavelength in front decreases
- ->Frequency INCREASES
- ->wavelength in back increase
- ->Frequency decreases
Pitch increases as frequency increases
