A wave is a something which can be described by a functional form ofy = f(x-vt) of f(x+vt)If that function is a sinosidal functionlikey = Asin(k*(x-vt)+phi) or Asin(k*(x+vt)+phi)then such wave is called sinosidal wave.

The sine wave or sinusoid is a function that occurs often in mathematics, physics, signal processing, audition, electrical engineering, and many other fields. Its most basic form is:

$y(t) = A \cdot \sin(\omega t + \theta)$

which describes a wavelike function of time (t) with:

• peak deviation from center  = A (aka amplitude)
• angular frequency ω, (radians per second)
• phase = θ
• When the phase is non-zero, the entire waveform appears to be shifted in time by the amount θ/ω seconds. A negative value represents a delay, and a positive value represents a "head-start".
