Homonym: waves (Signals)
Waves are disturbances that transfer energy through space or a medium, such as water or air. They can be classified into two main types: mechanical waves, which require a medium to travel through, and electromagnetic waves, which can move through a vacuum. Common examples of mechanical waves include sound waves and ocean waves, while examples of electromagnetic waves include light and radio waves.
Waves are characterized by their wavelength, frequency, and amplitude. The wavelength is the distance between two consecutive peaks, frequency refers to how many waves pass a point in one second, and amplitude measures the height of the wave. Understanding these properties helps explain various phenomena, such as music and light behavior.
