Waves made with springs




Waves in spring

When the left end of the spring vibrates, the vibration is transmitted to the other end.
A spring can vibrate horizontally or vertically.

Fixed-end reflection

When a wave reflects off a fixed-end, the phase of the wave is reversed.

Fixed-end reflection

Free-end reflection

On the other hand, when a wave is reflected at the free-end, the phase of the wave remains the same.
