Wave behavior at boundaries is crucial in understanding how waves interact with different media. Transmission, reflection, and polarization depend on the properties of the boundary and the wave type. These phenomena affect wave speed, orientation, and intensity.

Transverse waves can be polarized, restricting their oscillations to a single plane. This process can impact wave intensity, which is measured as average power transferred per unit area over one wave period. Understanding these concepts is essential for analyzing wave behavior in various scenarios.

#Wave-boundary interaction

#Transmission and reflection

Properties of the boundary separating two media determine whether a wave traveling from one medium to another will be transmitted, reflected, or both 🌊
Low-mass to high-mass string boundary results in both reflected and transmitted waves
Reflected wave inverts if transmitted wave speed decreases in the new medium
Reflected wave maintains orientation if transmitted wave speed increases in the new medium
Wave frequency remains constant when crossing a boundary between different media

#Wave polarization

Polarization can occur when transverse waves interact with surfaces, media, or openings
Transverse wave oscillations can be restricted to a single plane through polarization
Longitudinal waves, due to the direction of their oscillation, cannot be polarized

#Polarization and intensity

Wave intensity, the average power transferred per unit area over one wave period, may decrease due to polarization 📉
Power transferred per unit area quantifies wave intensity
Intensity calculation involves averaging power per unit area across one full wave period 🚫 Boundary Statements: Wave transmission and reflection at a boundary depend on boundary properties. Reflected waves can be inverted or maintain orientation based on the relative wave speeds in each medium. Transverse waves can be polarized, while longitudinal waves cannot due to their oscillation direction.
