- How does a standing wave form?
- Relevant Equations
- Newton's 3rd Law
I learned that standing waves form when the incident wave's frequency is equivalent to the reflected wave's frequency. But I also learned that according to Newton's 3rd law, when a wave hits a boundary, the reflected wave continues to travel in the opposite direction but has equal frequency and amplitude as the incident wave. But if this is the case, wouldn't the incident and reflected waves cancel each other out by destructive interference?
