c)
Explanation:
a) The speed of a wave is given by the following equation:
Where:
λ is the wavelength
f is the frequency
b) The harmonic wave has the following equation:
A is the amplitude (2 m)
k is the wavenumber (2π/λ)
ω is the angular frequency (2πf)
c) Here we need to find the heigth at x=3 m and t =10 s, so we need to find y(3,10).
