To determine the wavelength from the given equation, SetupY = 5sin(2π/5)(t - x), we can compare it to the general equation for a sinusoidal wave:
y = A sin(kx - ωt + φ),
where A is the amplitude, k is the wave number (2π divided by the wavelength λ), ω is the angular frequency (2π times the frequency f), t is time, x is position, and φ is the phase constant.
Comparing the two equations, we can see that the wave number in your equation is given by 2π/5. To find the wavelength, we can use the relationship between the wave number and wavelength:
k = 2π / λ.
From this, we can solve for λ:
λ = 2π / k.
Substituting k = 2π/5 into the equation, we get:
λ = 2π / (2π/5) = 5.
Therefore, the wavelength of the wave described by the equation SetupY = 5sin(2π/5)(t - x) is 5 units.
