The function y(x, t) = Asin(kx−ωt+ϕ) where x is in metres and t in seconds for
(a) tp = 3.5 s and (b) xp = 3.7m
3. The attempt at a solution
I don’t even know where to begin.
I know λ = 2pi/k
this is really disorienting. In the first graph, I’m given t = 3.5.
A = 3
y(x,t) = 3sin(kx-3.5ω)
In the second graph, y(x,t) = 3sin(3.7k – ωt)
Really, I don’t know how should I get started and I’m really frustrated.
I’m asked to find the wavelength. Is it 7m based off the first graph or do I have to utilize t = 3.5 and x=3.7?
