Title: Incomplete mechanism
Post by: DrC on October 14, 2004, 04:40:33 am
pretty good illustrative applet Hwang
http://www.phy.ntnu.edu.tw/java/propagation/propagation.html

but by what mechanism do we explain the segmentation of the propagated wave?
What happens to only allow the outgoing beam instead of the full width wavefront propagating out from the surface contact?

Yes. Nothing will  prevent full width wavefront propagating out from the surface contact!

However, those intensity will be much smaller compare to the intensity of the outgoing beam.

It will be too complicated if I drawed all the possible wavefront.

That much is certain but why?
In your illustration they just magically disappear : )

It's a great thing to teach but a shame to leave out something important.
I understand if you cannot illustrate what actually happens but wouldn't you agree that it is important to mention that the model is far from complete?
That reality is much more complicated. That more thought is required to understand it by the 'reader' than is immediately obvious.
