Now, see yesterday we talked about regular sea waves, nice sine curves coming, but as
you all know, if you really go to open ocean, you will never find a wave which is very
nice and sinusoidal, you will find wave which will probably look something like,
something like that. If you try to monitor it at some location, it will look like that or if
you try to take a snap shot also will look like that, it will not look like a nice and sine
curve. In other words, what will you find is that there is lot of irregularity, it does not at
all look like a sine curve, or one can say it is random
