Examples
Lessons
  1. Reflection from less dense medium
    A pulse is sent along a thick rope connected to a thin rope.

    Wave behavior at a boundary

    1. What happens when the pulse reaches the boundary?
    2. Is the reflected pulse erect or inverted?

      1. Reflection from less dense and denser medium
        A pulse is sent along a thick rope connected to thin rope which is tied to a wall.

        1. What happens at point where the ropes are connected?
        2. What happens at the point where the thin rope is connected to the wall?
