Summary In this paper we examine head waves and normally‐reflected (normal) waves from transition layers, and see what information they can give about the shapes of these layers. Examination of the waves’ spectra show that their low‐ and high‐frequency regions do not give the necessary information for determining the general shape of the layers. We suggest that this information may be obtained from the intermediate‐frequency (i ‐ f) regions. To test this we plot amplitude and phase spectra of head and normal waves from two different transition layers. The i‐f regions show certain features, which may be connected with the transition layers’ shapes. In order to reach a definite conclusion, further work needs to be done.
