This lecture covers wave interactions, focusing on the superposition principle and the differences between constructive and destructive interference. It explains how waves reflect at boundaries, either fixed or free, and introduces standing waves, highlighting nodes and antinodes. The lecture concludes with a summary of the key concepts discussed.
