Answer:
f = 127.48 Hz , T = 7.844 1⁻³ s , Ф = 3.38 , λ = 12.49 m
Explanation:
The general equation for the motion of a wave in a string is
y = A sin (kx -wt + fi)
the expression they give is
y = ym sin (0.503x + 801 t + 3.38 )
the veloicda that accompanies time is
w = 801 rad / s
angular velocity is related to frequency
w = 2π f
f = w / 2π
f = 801 / 2π
f = 127.48 Hz
The period is the inverse of the frequency
T = 1 / f
T = 1 / 127.48
T = 7.844 10⁻³ s
the csntnate of phase fi is the independent term
Ф = 3.38
the wave vector accompanies the position k = 0.503 cm
ka = 2pi /λ
λ = 2 π / k
λ = 2 π / 0.503
λ = 12.49 m
