14. The distance between one crest and the next crest is the wave's

Wavelength! Imagine each wave as a joyful dancer performing across the ocean, with the distance from one peak to the next being the space between their graceful leaps. It’s a fundamental concept in physics and helps determine how waves interact with each other—like a rhythmic dance competition! Now, think about the real-world applications of wavelength, such as in telecommunications. Different wavelengths carry radio, TV, and mobile signals, allowing us to communicate and stream our favorite shows. Next time you binge-watch your favorite series, remember those waves are working tirelessly to deliver entertainment straight to your devices!
