I have problem figuring out the reflection of a pulse on a rope with a fixed point.
Do you know some websites to find animations about it?

- Pulse Reflection Rope
In summary, when a pulse reaches the end of a rope, it reflects back in the opposite direction due to the rope's boundary conditions. The reflection can be affected by factors such as tension, density, thickness, and the angle of incidence. The amplitude of the reflected pulse is equal to the original pulse, and the speed of the pulse can affect the reflection by causing inversion if it is greater than the reflected pulse's speed. There is also a difference between fixed and free end reflections, where a fixed end reflection causes inversion and a free end reflection does not, due to different boundary conditions.

Maybe more :D
Thank you, both the animation and discription (Newton's third law) at the page were what I needed to understand it.

1. How does a pulse reflect on a rope?
When a pulse reaches the end of a rope, it reflects back in the opposite direction. This is due to the boundary conditions of the rope, where the end acts as a fixed point and the pulse is unable to continue past it.
2. What factors affect the reflection of a pulse on a rope?
The reflection of a pulse on a rope can be affected by various factors such as the tension, density, and thickness of the rope. Additionally, the angle at which the pulse hits the end of the rope can also impact the reflection.
3. How does the amplitude of the reflected pulse compare to the original?
The amplitude of the reflected pulse is equal to the amplitude of the original pulse. This is known as the law of reflection, where the angle of incidence is equal to the angle of reflection and the amplitudes remain the same.
4. Can the speed of the pulse affect its reflection on a rope?
Yes, the speed of the pulse can affect its reflection. If the speed of the pulse is greater than the speed of the reflected pulse, the reflected pulse will be inverted. If the speed of the pulse is equal to the speed of the reflected pulse, there will be no inversion.
5. What is the difference between a fixed and free end reflection on a rope?
A fixed end reflection occurs when the end of the rope is fixed, and the reflected pulse is inverted. A free end reflection occurs when the end of the rope is free to move, and the reflected pulse is not inverted. This is due to the difference in boundary conditions at the end of the rope.
