Wavelength

Real World Example

Imagine trying to space out a row of identical books evenly on a shelf. This is similar to the concept of wavelength because just like the distance between the edges of two adjacent book covers, the wavelength is the distance between the crests of two adjacent waves. In this analogy, each book represents a wave crest, and the space between the edges of two books is like the wavelength, ensuring consistent spacing across the entire row.
