Wave action...
Jun. 3rd, 2007 04:37 pm
The Aquarium has a new exhibit on wave action - this double tank demonstrates the difference between wind waves and tsunami waves. Gareth is observing what both kinds of waves look like while at sea (wind waves may be higher, but have a very short wave-length - tsunami waves may be only 2-3 tall, but have a wavelength of hundreds of miles).
(and yes, we did go two days in a row...)
