Sep 12, 2022 · We can define a constant of a material that describes the speed of light in it, called the index of refraction n: \[n=\dfrac{c}{v} \label{index} \] where \(v\) is the observed speed of light in the material.
The speed of light depends strongly on the type of material, since its interaction varies with different atoms, crystal lattices, and other substructures. We can define a constant of a material that describes the speed of light in it, called the index of refraction n:

Waves can be classified according to the medium through which they propagate. mechanical waves 1. …require a material medium. Sound is the most important example of a mechanical wave. Sound waves cannot travel through a vacuum. electromagnetic waves 1. …propagate through the electric and magnetic fields that are everywhere in space. Light is the mo...
Waves can be classified according to the type of disturbance — meaning its relative direction or shap. There is a lot that can be said about this organizational scheme. I'm starting this part of this section with a quick summary in table form followed by a rather detailed follow up.
A transverse waveis one in which the direction of the disturbance is perpendicular to the direction of propagation. The word transverse describes something pointing in a sideways or lateral direction. As dynamic phenomena, waves are better represented with animations than with static images. Click on the static image below to see a transverse wave ...

Waves can be classified according to what they appear to be doing. traveling waves 1. …are waves that appear to be propagating. This might seem like a distinction made by the Department of Redundancy Department, since propagation is a key part of the definition of a wave, but there actually are waves that do not appear to be going anywhere. standin...
Mar 14, 2021 · The concepts of wave packets, as well as their phase, group, and signal velocities, are of considerable importance for propagation of information and other manifestations of wave motion in science and engineering which warrants further discussion at this juncture.
Mar 13, 2020 · Electromagnetic (EM) waves, also called electromagnetic radiation, are created by the coupling of oscillating electric and magnetic fields, whose directions are perpendicular to each other. The direction of propagation of the EM wave is perpendicular to both the electric and magnetic field vectors.
Propagation is the intervening process whereby the information-bearing wave, or signal, is conveyed from one location to another. In communications, propagation is the link between the transmitter and the receiver, while for propagation occurs between the transmitter and the target to be sensed and the target and the receiver.
