Assuming the equation represents a standing wave on the string, we can determine some properties of the wave.
The equation y(x, t) = 0.01m sin [(62.8m-1)x] cos[(628s-1)t] can be broken down into two parts: the spatial part and the temporal part.
The spatial part is given by sin [(62.8m-1)x], which represents the position of the string at a given point x. The frequency of the spatial part is given by the coefficient in front of x, which is 62.8 m^-1. The wavelength of the wave can be calculated using the formula λ = 2π/k, where k is the wave number. In this case, k = 62.8 m^-1, so the wavelength is λ = 2π/(62.8 m^-1) = 0.1 m.
The temporal part is given by cos[(628s-1)t], which represents the time dependence of the wave. The frequency of the temporal part is given by the coefficient in front of t, which is 628 s^-1. The period of the wave can be calculated using the formula T = 2π/ω, where ω is the angular frequency. In this case, ω = 628 s^-1, so the period is T = 2π/(628 s^-1) = 0.01 s.
Since the wave is in its fifth harmonic, the wavelength of the wave is equal to 5 times the fundamental wavelength (λ_1), and the period of the wave is equal to 5 times the fundamental period (T_1).
Therefore, the fundamental wavelength is λ_1 = λ/5 = 0.1 m/5 = 0.02 m, and the fundamental period is T_1 = T/5 = 0.01 s/5 = 0.002 s.
In summary, the wave has a wavelength of 0.1 m, a period of 0.01 s, a fundamental wavelength of 0.02 m, and a fundamental period of 0.002 s.
