An asymptotic method is used to find the eigenvalues and eigenfunctions of the reduced wave equation in slender cavities, and to find the modes of propagation in slender tubes. The results for the eigenvalues of prolate spheroids are found to be in good agreement with those computed numerically by Chang.
