PHI … WebJul 5, 2024 · The answer is actually very dependent on how you pluck the string. If you pluck it closer to the center, you put more energy into the lower modes. Pluck it near either end, and you have more higher harmonics. And then there's the overtone techniques, which intentionally squelch lower harmonics, leaving only higher harmonics.

WebJan 30, 2024 · The spherical harmonics can be accessed by the function Ynm. In the list of arguments, 𝑙 comes first and 𝑚 second. The order of the angles is (𝜃,𝜑): Y = Ynm (l, m, θ, φ) The spherical harmonics can be expressed in terms of trigonometric functions. We can easily list them using SymPy, in this case, up to 𝑙=3: WebThe spherical harmonics Y n m (theta, phi) are the angular portion of the solution to Laplace's equation in spherical coordinates where azimuthal symmetry is not present. Caution; Care must be taken in correctly identifying the arguments to this function: θ is taken as the polar (colatitudinal) coordinate with θ in [0, π], and φas the ...
