The Electromagnetic Spectrum: Understanding the Wavelength Range of Four Regions

The electromagnetic spectrum is a vast range of frequencies and wavelengths that make up the electromagnetic radiation emitted by various sources in the universe. It encompasses all types of electromagnetic waves, from low-frequency, long-wavelength waves to high-frequency, short-wavelength waves. In this article, we will delve into the wavelength range of four regions in the electromagnetic spectrum, exploring their characteristics, properties, and applications.

Understanding the Electromagnetic Spectrum

The electromagnetic spectrum is a continuous range of frequencies and wavelengths that are classified into different regions based on their characteristics and properties. These regions include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Each region has a unique wavelength range, frequency, and energy level, which determines its behavior and interaction with matter.
