A single wave pulse is sent along a thick rope that's tied to a thin rope, which in turn is attached to a wall. Reflection of the wave will occur at both points A (where the thick rope is attached to the thin rope) & point B (where the thin rope is attached to the wall)

Question

Which point will the reflected wave be inverted & which point will it be erect.

At point A it will remain erect because there is free movement, at point B it will invert because it's attached to a solid perpendicular surface.

Is that correct?

Thanks :)
