Wave behavior at a boundary - Waves

Wave behavior at a boundary

Lessons

Notes:

In this lesson, we will learn:

  • Reflection at boundaries
  • Properties of the reflected waves

Notes:

As waves move from one medium to another partially reflected and partially refracted (transmitted).
  • Reflection; The process of bouncing off the boundary between two media.
  • The wave striking the boundary is called the incident wave
  • The wave bouncing off the boundary is called the reflected wave.
  • Refraction; Transmission of the energy from one medium to another. Sound waves change speed due to the temperature.
  • Water waves speed changes according to the depth.
  • Spring thickness changes the speed of the waves.
  • Wave reflecting from less dense medium is ERECT.
    Example; reflection from thinner rope into thicker rope

  • Wave reflecting from denser medium is INVERTED.
    Example; reflection from WALL or from a THICK rope
