The electromagnetic spectrum encompasses a range of wavelengths and frequencies, from radio waves to gamma rays. It includes visible light, the only part detectable by the human eye, and extends to waves used in communication, medical diagnostics, and more. Understanding the spectrum's properties, such as the inverse relationship between wavelength and frequency, is crucial for leveraging its applications in various fields.
