Physics amplitude formula

Webb10 apr. 2024 · The following formula is used to compute amplitude: x = A sin (ωt+ϕ) Where, x = displacement of the wave, in metres. A = amplitude of the wave, in metres. ω = angular frequency of the wave, in radians. t = time, in seconds. ϕ = phase shift, in radians. Webb14 apr. 2024 · The maximum wave amplitude is approximately 1.5 times the carrier wave amplitude at the position near the wave-maker. We set up nine gauges from 2 to 10 m, and the maximum wave amplitude is expected to be observed at 9 m according to the theory. The physical wave tank is 20 m long and 1 m wide, and the water depth is 0.5 m.
