Answer: Amplitude = 50.25m, angular frequency ([tex]y = A sin (kx -wt)[/tex]) = 240rad/s, wave number (k) = 0.30, wavelength (λ) = 0.047m
Explanation: The equation of wave from the question (corrected) is
[tex]y = 50.25 sin ( 0.30x - 240t)[/tex]
by comparing this to the general equation of a wave (in the negative direction) is given below
[tex]y=Asin (kx - wt )[/tex]
a)
we have that A = 50.25m
b)
-ωt = 240t, thus
ω= 240 rad/s
c) kx = 0.30x , thus
k= 0.30
d) to get wavelength, we use the formulae below
k = 2π/λ
0.30 = 2* 3.142/λ
λ = 2 * 3.142/ 0.30
λ = 0.047m
