(a) Scattering at the spatial interface between two media M1 and M2: reflected waves propagate back into medium M1 while transmitted ones enter medium M2. (b) Scattering at a temporal interface (Medium M1 is suddenly switched to medium M2) also generates forward and backward waves: in this case, however, they both propagate within the new medium M2.
