Physical significance of an equation of wave

Click For Summary
SUMMARY

The discussion centers on the physical significance of the wave equation, specifically the equation \(\frac{\partial^2 y}{\partial t^2} = v^2 \frac{\partial^2 y}{\partial x^2}\), where \(v\) represents the wave propagation velocity. Participants emphasize the need for a physical interpretation of each step in the derivation rather than relying solely on mathematical manipulation. The conversation suggests that understanding the physical implications of the wave equation enhances comprehension of wave behavior in various contexts.

We can mathematically derive the equation of wave,
\frac{\partial^2 y}{\partial t^2} = v^2 \frac{\partial^2 y}{\partial x^2}, where v is the velocity of wave propagation.
Can we prove this equation physically (not just taking derivatives of the equation of wave, but making physical meaning in every steps)?
