Answer :
The wavelength of the water wave having a amplitude of 1.2 meters every 0.4 seconds is 1.8 m .
What is wavelength?
Wavelength is the total distance traveled by a wave in one cycle.
To calculate the wavelength of the wave, we use the formula connecting
speed, wavelength, and Period.
Formula:
- v = λ/T........... Equation 1
Where:
- v = Velocity of the wave
- λ = Wavelength
- T = Period
Make λ the subject of the equation
- λ = vT............ Equation 2
From the question,
Given:
- v = 4.5 m/s
- T = 0.40 s
Substitute these values into equation 2
- λ = (4.5×0.4)
- λ = 1.8 m
Hence, The wavelength of the water wave having a amplitude of 1.2 meters every 0.4 seconds is 1.8 m .
