Spectrum

The electromagnetic spectrum encompasses all types of electromagnetic radiation, ranging from very long radio waves to extremely short gamma rays. It includes visible light, radio waves, X-rays, and more, distinguished by their wavelengths and energies. Each type of radiation has unique uses and properties; for example, radio waves carry TV signals, while X-rays help in medical imaging. The spectrum helps us understand how different waves behave and interact with matter, enabling technologies like communication, medical diagnostics, and astronomy. It’s a continuous range, with no clear boundary between the various types, reflecting the diverse ways electromagnetic energy manifests.
