Frequency Spectrum

The frequency spectrum is a way to visualize all the different types of signals, like radio waves, sound, or light, based on their frequencies. Think of it as a chart that shows how often certain signals occur over a range of frequencies. For example, radio stations broadcast at specific frequencies, and the spectrum helps us understand where those signals are. It helps engineers and scientists organize and analyze various electromagnetic signals to ensure they don't interfere with each other and to optimize communication systems. Essentially, it's a map of all the different "pitches" or frequencies in the electromagnetic world.
