What is dispersion in electromagnetic waves?
Dispersion occurs when sinusoidal waves of different wavelengths have different propagation velocities, so that a wave packet of mixed wavelengths tends to spread out in space.
What is the process of wave dispersion?
Wave dispersion is the same as track-and-field dispersion: When waves travel at different speeds, the disturbance must spread over time unless some other mechanism intervenes.
What are the 7 types of electromagnetic waves?
In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.
What is absorption and dispersion?
The real part of this complex number relates to dispersion, and the imaginary part relates to absorption. Dispersion and absorption occur whenever electromagnetic radiation interacts with matter. Only in vacuum, where there is no matter to interact with light, is there no dispersion and no absorption.
