Hello Peter,

 

Yes, I’d say you do.

I read that line too, and thought it would be even better if it read:

“If the eyes were at water level, then, provided the moon were visible _at all_, its reflection would surely be, too.”

 

By the by, the eye position at water level is the only place where the reflection _is_ the same as the original, only upside down. That is, no perspective difference occurs – it cannot, because the eye coincides with its own reflection.

It may occur to some readers on this list that many microwave, and some shortwave, radio propagation problems should be solved using the same reasoning.

 

Happy ray-tracing!

Rudolf

Thus, provided the moon itself was visible (and not obscured by houses) the reflection must also be visible. Am I understanding it correctly?
