Path Difference and Interference
Difference in path lengths of waves due to boundary conditions can lead to constructive or destructive interference.

Impedance
Changes in the material type a wave passes through can cause both reflection and transmission of the wave at the boundary.

Dispersion of Light
A prism separates light into component colors due to the different index of refraction of difference wavelengths.
