the frequency equation to determine how many times in one second
the water wave travels down and back the lake. | | (0.0K) | | The
lake acts as a closed basin of water. Sketching the first harmonic
of a seiche (wave), you can see that at both ends there will
be a node. | | (0.0K) | | With
nodes at the ends, one half wavelength fits in the lake. Consequently,
one wavelength is twice the length of the lake, 120 mi. To calculate
the velocity, use the following equation. | | (0.0K) | | This
velocity is about 30 mph. If the log were to 'ride' this wave
to the far end of the lake, it would take two hours to complete
the trip. | | (0.0K) | (0.0K) | (0.0K) | (0.0K) | (0.0K) |
