To find the wavelength, frequency, and angular frequency of the given function y=2sin(2x)(100t-x/30), we need to first identify the parameters of the function.
The general form of a sinusoidal function is y = A sin(Bx + C), where A is the amplitude, B is the angular frequency, and C is the phase shift.
In this case, the function is y = 2sin(2x)(100t-x/30).
Comparing this to the general form, we can see that: - A = 2 (amplitude) - B = 2 (angular frequency) - C = 0 (no phase shift)
The wavelength (λ) of a sinusoidal function is given by the formula λ = 2π/B. In this case, B = 2, so the wavelength is: λ = 2π/2 = π
The frequency (f) of a sinusoidal function is given by the formula f = B/2π. In this case, B = 2, so the frequency is: f = 2/2π = 1/π
The angular frequency (ω) of a sinusoidal function is given by the formula ω = 2πf = 2πB. In this case, B = 2, so the angular frequency is: ω = 2π*2 = 4π
Therefore, the wavelength is π, the frequency is 1/π, and the angular frequency is 4π.

Wave length (λ):
The wavelength is given by:
``` λ = 2πv / ω ```
where:
- v is the wave speed - ω is the angular frequency
From the given equation, we can see that:
``` ω = 200π t - πx/30 ```
and
``` v = dx/dt = 100 ```
Substituting these values into the equation for wavelength, we get:
