A wave is a disturbance that travels or propagates from the place where it was created. Waves transfer energy from one place to another, but they do not necessarily transfer any mass. Light, sound, and waves in the ocean are common examples of waves. Sound and water waves are mechanical waves; meaning, they require a medium to travel through.

Distributing the factor of 2π λ, and using Equation 1.2.3, we get the final form of the wave function of a 1-dimensional harmonic wave: f(x, t) = Acos(2π λ x ± 2π T t + ϕ) It is common to write this wave function in more compact ways.

Summary. A sinusoidal wave signal is a type of continuous wave that has a smooth and repetitive oscillation. It is based on the sine or cosine trigonometric function, which describes the curve of the wave.
