Radioacoustics, or geometrical acoustics, is similar to geometric optics. The main reason is that when the wavelength is very small (compared with the space or object scale), the energy propagates along a straight line, that is, the diffraction phenomenon is neglected, and only the reflection and refraction of the sound line are considered. This is a very effective method in many cases. For example, when studying indoor reflective surfaces, performing nondestructive testing in solids, and detecting in liquids, etc., the concept of sound rays is used.
