Amplitude ratios and energy ratios for various reflected and refracted waves have been obtained for a longitudinal wave impinging obliquely at a plane discontinuity of two linear micropolar elastic solids in welded contact.

Which waves can be refracted?

Waves change speed when they pass across the boundary between two different substances, such as light waves refracting when they pass from air to glass. This causes them to change direction and this effect is called refraction. Water waves refract when they travel from deep water to shallow water (or vice versa).

Can Longitudinal be reflected?

When a wave travelling in a homogeneous medium meets a boundary of some other medium, it has a tendency to travel in the opposite direction. This phenomenon is called the reflection of the wave (or energy). Both light waves (transverse waves) and sound waves (longitudinal waves) exhibit this phenomenon.
