Diket: Pers gelombang y = 15 sin π (5t - 3x ) Dit: λ.......? y = 15 sin π (5t - 3x) y = 15 sin (5πt - 3πx) y = A sin (wt - kx) k = 3π λ = 2π/k λ = 2π/3π λ = 2/3 cm λ = 0,67 cm
Pers gelombang y = 15 sin π (5t - 3x )
Dit: λ.......?
y = 15 sin π (5t - 3x)
y = 15 sin (5πt - 3πx)
y = A sin (wt - kx)
k = 3π
λ = 2π/k
λ = 2π/3π
λ = 2/3 cm
λ = 0,67 cm
