we know y=asin(ωt−kx) is
equation of wave
which velocity will be (ω/k)
But what will be the velocity of
a wave that is created from
superposition of two sine wave of
different velocity like bellow
y=5sin(6t−x)cos(13t−6x) ?

we know the equation of a simple harmonic wave
going to left to right is,
y=asin((2π)/λ)(vt−x)
if we put t=0 and x=0 ,
we get y=0
and if we put t=0 and x=0.25λ ,
we get y= a !!
But How could this be possible?
How could right side particles start oscillating
before the left ones?Don′t we need a
certain time gap for right side particles
to start oscillating??

Ocean waves are observed to
travel along the water surface
during a developing storm.
A Coast Guard weather station
observes that there is a vertical
distance from high point to low
point of 4.6 meters and horizontal
distance of 8.6 meters between
adjacent crests.The waves splash
into the station once every 6.2 seconds
Determine the frequency and
the speeed of these waves.
