Periodic Wave
Definition
A periodic wave is a type of wave that repeats itself in both time and space. It has a consistent pattern and can be described by its amplitude, frequency, and wavelength.
Analogy
Imagine a group of synchronized swimmers performing a routine in a pool. As they move together, their movements repeat in a rhythmic pattern. Similarly, a periodic wave repeats its shape and characteristics as it travels through space.
Related terms
Amplitude: Amplitude refers to the maximum displacement or height of a wave from its equilibrium position. It represents the intensity or strength of the wave.
Frequency: Frequency is the number of complete cycles or oscillations that occur in one second. It affects how many times an object vibrates back and forth within a given time period.
Wavelength: Wavelength is the distance between two consecutive points on a wave that are in phase with each other, such as crest to crest or trough to trough.
