We are all at different levels of research, some researching different areas.
I think one important thing to keep in mind is Waves! All waves! Electromagnetic, or Waves on the beach all exhibit the same characteristics!
Some basics on Waves:
Standing Waves:
Another Interesting video:
Simple but effective:
My point of showing these videos is to show that two waves when interfering can very easily create different effects just from a small amount of tuning!
A Coil of Wire, carrying a Current will produce a Magnetic Field, this very Magnetic Field needs to be thought of as a Wave, subject to all the same laws that the above Videos show. This Magnetic Interference is Electromagnetic Induction!
Types of Waves:
- Longitudinal Waves - Movement of the particles are parallel to the motion of the energy. Sound waves moving through the air is an example of this type of wave.
- Transverse Waves - movement of the particles are at right angles (perpendicular) to the motion of the energy. Movement of a wave through a solid object like a stretched rope or a trampoline is an example of this type of wave.
- Surface Waves - particles travel in a circular motion. These waves occur at interfaces. Examples include waves in the ocean and ripples in a cup of water. One consequence of occurring at an interface is that the motion of the particles diminish with distance from the interface. The further from the interface the smaller the rotation of the particles until as some distance from the surface, there is no more movement or energy propagation.
- Shear Waves - Can travel in all directions away from the epicentre of an Earthquake. Shear waves on the other hand have larger amplitudes and travel at a slower
- Lamb Waves - Lamb waves propagate in solid plates. They are elastic waves whose particle motion lies in the plane that contains the direction of wave propagation and the plate normal (the direction perpendicular to the plate)
- Love Waves - In elastodynamics, Love waves, named after Augustus Edward Hough Love, are horizontally polarized surface waves. The Love wave is a result of the interference of many shear waves (S–waves) guided by an elastic layer, which is welded to an elastic half space on one side while bordering a vacuum on the other side.
- P Waves - A type of elastic wave, and are one of the two main types of elastic body waves, called seismic waves in seismology, that travel through a continuum and are the first waves from an earthquake to arrive at a seismograph.
- Rayleigh Waves - A type of surface acoustic wave that travel along the surface of solids. They can be produced in materials in many ways, such as by a localized impact or by piezo-electric transduction, and are frequently used in non-destructive testing for detecting defects
I hope this helps everyone!
