Light does not carry any charge itself, so it does not attract or repel charged particles like electrons. Instead light is an oscillating electric and magnetic field. If you take an electron and put it in a static electric field (e.g. around a Van de Graaff Generator) then the electron feels a force due to the field and will move.
May 24, 2024 · The wave equation included physical constants from both electricity and magnetism, and extracting the wave speed from this equation resulted in a number Maxwell was already familiar with – the speed of light. It is traditional to denote this speed with a lower-case 'c': c = 3.0 ×108m s (2.1.1) (2.1.1) c = 3.0 × 10 8 m s.

All waves are known to undergo reflection or the bouncing off of an obstacle. Most people are very accustomed to the fact that light waves also undergo reflection. The reflection of light waves off of a mirrored surface results in the formation of an image. One characteristic of wave reflection is that the angle at which the wave approaches a flat ...
All waves are known to undergo refraction when they pass from one medium to another medium. That is, when a wavefront crosses the boundary between two media, the direction that the wavefront is moving undergoes a sudden change; the path is "bent." This behavior of wave refraction can be described by both conceptual and mathematical principles. Firs...
Reflection involves a change in direction of waves when they bounce off a barrier. Refraction of waves involves a change in the direction of waves as they pass from one medium to another. And diffractioninvolves a change in direction of waves as they pass through an opening or around an obstacle in their path. Water waves have the ability to travel...
Apr 10, 2022 · Example 5.1. 1 5.1. 1: Deriving and Using the Wave Equation. The equation for the relationship between the speed and other characteristics of a wave can be derived from our basic understanding of motion. The average speed of anything that is moving is: average speed = distance × time average speed = distance × time.
Dec 28, 2020 · In plain terms, electromagnetic waves are simply what we know as light. Unlike most waves, however, electromagnetic waves do not require a medium through which to propagate. Photons or electromagnetic radiation exhibit what is called particle-wave duality. They can act like particles or waves.
It’s not as odd as it might seem, either. Particles and waves are sometimes conceived as opposites, but they’re not. Also, light is not the only thing that exhibits behavior of both particles and waves. Other quantum entities also have this behavioral duality, and wave-particle duality is a key focus of the study of quantum mechanics.

The fields vibrate at right angles to the direction of movement of the wave, and at right angles to each other. Because light has both electric and magnetic fields, it's also referred to as electromagnetic radiation. Electromagnetic radiation doesn't need a medium to travel through, and, when it's traveling in a vacuum, moves at 186,000 miles ...
