1.
If the time interval required to travel from A to B is 2 seconds, determine the speed of the ìgbì ìyípadà.
A mọ̀:
ijinna A-B = 6 meters
Aago igba A-B = 2 aaya
Fe: Speed of transverse wave
Ojutu:
1 igigirisẹ 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 mitas / 4 = 1.5 meters.
Awọn 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 = igigirisẹ, f = igbohunsafẹfẹ, T = period
The speed of wave :
v = 1.5 meters / 0.5 sekondisi
v = 3 meters/ seipo
2. If the time interval required to travel from A to B is 8 seconds, determine the speed of transverse wave.
A mọ̀:
There are two wavelength.
1 igigirisẹ (λ) = 2 x 4 meters = 8 mitas
Period (T) = 8 sekondisi / 2 awọn igbi gigun = 4 seconds / igigirisẹ
A fẹ́: Speed of wave (v)
Ojutu:
The speed of wave calculated using the equation of the speed of wave :
v = f λ = λ/T
v = 8 meters / 4 sekondisi
v = 2 meters/ seipo
