The Helmholtz equation often arises in the study of physical problems involving partial differential equations (PDEs) in both space and time. The Helmholtz equation, which represents a time-independent form of the wave equation, results from applying the technique of separation of variables to reduce the complexity of the analysis. For example, consider the wave equation WebThe F1 and F2 are related, respectively, to the height of the tongue (high frequency F1 = low vowel, low frequency F1 = high vowel) and to the backness/frontness of the tongue (high frequency F2 = front vowel, low frequency F2 = low vowel).
