Thanks for this, I find the internet is getting more and more cluttered. Hard to find good information.

Good stuff, as always!

I don't foresee needing this formula, but if I do need it, I know where to find it. Thanks

nice work

VERY GOOD!

Id go through the integration to calculate it but nice to have the answer handy

Painting corrugated area resonates.

A better example would be figuring the Road Distance on a Road Map or Topo Map which is what I thought this video was about.

How did you find it? Is it used for light distance within a toslink cable?

is this formula exact or a close enough approximation? if it's exact, it's interesting that it's simply a function of amplitude/wavelength ratio.
