Q: A two-dimensional water wave spreads in circular wave fonts. Show that the aplitude A at a distance r from the initial disturbance is proportional to [tex]\frac{1}{\sqrt{r}}[/tex]. (Hint: Consider the energy carried by one outward moving ripple.)
Comments:
Let's consider the energy carried by one outward-moving ripple:
[tex]E_\lambda = \frac{1}{2} \mu \omega^2 A^2 \lambda[/tex]
and I suppose there is another wave directly across the origin for some particle. But how do I relate this to r?
thanks!
