Seiche
A seiche is an oscillating standing wave in a body of water. The term seiche pronounced saysh) can be understood by the sloshing of water back and forth in a swimming pool. The same phenomenon happens on a much larger scale in vast bodies of water including bays and lakes. A seizure can happen in any enclosed or semi-enclosed body of water.
A transverse sinusoidal wave is generated at one end of a
long, horizontal string by a bar that moves up and down through
a distance of 1.00 cm. The motion is continuous and is repeated
regularly 120 times per second. The string has linear density 120
g/m and is kept under a tension of 90.0 N. Find the maximum
value of (a) the transverse speed u and (b) the transverse component
of the tension t.
(c) Show that the two maximum values calculated above
occur at the same phase values for the wave.What is the transverse
displacement y of the string at these phases? (d) What is the
maximum rate of energy transfer along the string? (e)What is the
transverse displacement y when this maximum transfer occurs?
(f ) What is the minimum rate of energy transfer along the string? (g) What is the transverse displacement y when this minimum
transfer occurs?
