Electromagnetic Spectrum
The electromagnetic spectrum is the range of all types of electromagnetic radiation, which includes visible light, radio waves, microwaves, infrared light, ultraviolet light, X-rays, and gamma rays. These waves travel at the speed of light and vary in wavelength and frequency. In atomic structure, energy levels of electrons can absorb or emit specific electromagnetic wavelengths, leading to chemical reactions and the colors we see. Understanding the spectrum helps in various fields, from communication (radio and microwaves) to medical imaging (X-rays), and is fundamental to the study of physics and chemistry.
