Understand the relationship between the source charge, the medium and the electromagnetic wave. The wavelength, the distance between successive wave peaks, and the frequency, the number of wave cycles...Understand the relationship between the source charge, the medium and the electromagnetic wave. The wavelength, the distance between successive wave peaks, and the frequency, the number of wave cycles per second, are inversely related; as one increases, the other decreases. By integrating these concepts into the classroom, educators can inspire curiosity and a deeper understanding of the physical world, preparing students for further exploration in science and technology.
