| Oct 20, 2017 at 18:53 | comment | added | Majid | @LucJ.Bourhis the principle is still valid under the presence a small wind! is that right? | |
| Oct 20, 2017 at 18:16 | comment | added | user154997 | The problem is that I don't know how to explain that without non-trivial math but appetizer: yes, a modified form holds, to be precise a modified form of the Helmholtz formula, of which the Huygens-Fresnel principle is just a consequence. | |
| Oct 20, 2017 at 15:56 | comment | added | Majid | @LucJ.Bourhis Ok then :) I am looking forward to it then! | |
| Oct 20, 2017 at 15:54 | comment | added | user154997 | no, no, I said nothing so far: just wanted to be sure what you had in mind. I'll try to provide an answer later. | |
| Oct 20, 2017 at 15:53 | comment | added | Majid | @LucJ.Bourhis Indeed my wind creates a steady uniform current which is not so strong to make a strong turbulence on water. You mean in this case the principle is not valid? | |
| Oct 20, 2017 at 15:43 | comment | added | user154997 | I thought so. @Densch answer is correct as soon as the wind is strong enough to create an instability, and fair enough, if the wind is strong enough to create a current, it will be unstable. A practical realisation of what you had in mind would be an incoming stream into and an outgoing stream out of the pond which would induce a steady uniform current. Correct? | |
| Oct 20, 2017 at 15:39 | comment | added | Majid | @LucJ.Bourhis Yes, it is what I had in mind! When the wind is so small, each wavefront is still around the point of falling the stone. | |
| Oct 20, 2017 at 15:10 | comment | added | user154997 | Would it be possible that you actually had in mind that the wind would create a steady current in the water? A current in the direction of the wind of course. | |
