What is occurring when one tunes in a 'station' on the radio? Magic? No. Digital? No. A natural phenomena harnessed by people to communicate. Wavelength. All kinds, visual, hearing wavelength. Sonar is wavelength. Dolphins have a highly sophisticated society that communications due to wavelength. But. Then so do humans. Would you hear a word someone would say to you without wavelength? Of course not. Wavelength is very important. Like water, it is abundant throughout Earth and vital to life, especially plants. Even people need Vitamin D. It comes from the sun.
