Vitesse des ondes transversales – problèmes et solutions
1.
If the time interval required to travel from A to B is 2 seconds, determine the speed of the onde transversale.
Connu :
Distance A-B = 6 meters
Intervalle de temps A-B = 2 secondes
Voulait: Speed of transverse wave
Solution:
1 Longueur des ondes has 1 crest and 1 trough. There is 4 wavelength between A and B. Distance between A and B is 6 meters so that 1 wavelength (λ) = 6 mètres.s / 4 = 1.5 meters.
Le time interval required to travel from A to B is 2 seconds so that the time interval required to travel 1 wavelength = period (T) = 2 seconds / 4 = 0.5 seconds.
The equation of the speed of wave :
v = λ f = λ / T
v = speed of wave, λ = Longueur des ondes, f = fréquence, T = period
The speed of wave :
v = 1.5 meters / 0.5 second
v = 3 meters/Je saiscond
2. If the time interval required to travel from A to B is 8 seconds, determine the speed of transverse wave.
Connu :
There are two wavelength.
1 Longueur des ondes (λ) = 2 x 4 meters = 8 mètress
Period (T) = 8 second / 2 longueurs d'onde = 4 seconds / Longueur des ondes
Recherché : Speed of wave (V)
Solution:
The speed of wave calculated using the equation of the speed of wave :
v = f λ = λ/T
v = 8 meters / 4 second
v = 2 meters/Je saiscond
