Wave Behavior and Reflection Concepts

The video tutorial explains wave boundary behavior, focusing on how waves interact with different media. It covers fixed end and free end reflections, detailing how incident and reflected pulses behave. The tutorial also discusses wave behavior when transitioning between less dense and more dense media, highlighting changes in speed, wavelength, and amplitude. Key rules of boundary behavior are summarized, emphasizing that frequency remains constant across boundaries while speed and wavelength vary depending on the medium's density.

What is the term used to describe how waves behave when they encounter a boundary?
