A tsunami acts like a shallow-water wave because its wavelength is so large

[sniffnoy]

Random fact of the day: The velocity of a tsunami equals sqrt(g*d), where d is the depth of the water beneath it.
Random fact of the day #2: Joshua Norton's middle name was Abraham.

When you're not dealing with integers?

Precisely.

Actually, wouldn't it be natural numbers? Or basically any discrete set with a lower bound?

[sniffnoy.livejournal.com]

Well, yeah. But trying to use it with rational numbers or real numbers will especially get you into a whole lot of trouble... (yes, I've seen people try to do this. Which was why I made that comment in the first place.)

Is the speed of a tsunami equal to sqrt(g*d) or proportional to sqrt(g*d)?

[sniffnoy.livejournal.com]

The website said equal...
