Electromagnetic waves are waves of oscillating electric and magnetic fields that propagate through space. Unlike mechanical waves, electromagnetic waves do not require a medium to travel through and can propagate in a vacuum. They are produced by the acceleration of charged particles and exhibit characteristics such as wavelength, frequency, and speed. Here are some key features and properties of electromagnetic waves: 1. Electromagnetic Spectrum: The electromagnetic spectrum is the range of all possible wavelengths or frequencies of electromagnetic radiation. It encompasses different types of electromagnetic waves, each with its own characteristics and applications. The spectrum includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays, listed in order of increasing frequency or decreasing wavelength. 2. Wavelength and Frequency: Electromagnetic waves have a characteristic wavelength (λ) and frequency (f). The wavelength is the ...
