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.
May 24, 2024 · Mathematics and experiments show that light is a transverse wave – the electric and magnetic field vectors point in directions that are perpendicular to the direction of motion of the light wave (and as it turns out, they also rare always perpendicular to each other). Figure 2.1.1 – Electromagnetic Wave. The red arrows in the figure above ...
16 hours ago · Does light behave more like a particle, or like a wave? Today we know the surprising answer. Here's why it took so long to get there. From the most distant stars in the sky to the screen in front ...
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.

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...
Waves with longer wavelengths have lower frequencies. Mathematically, we can express this as. c = λf c = λ f. where the Greek letter for “l”—lambda, λ—is used to denote wavelength and c is the scientific symbol for the speed of light. Solving for the wavelength, this is expressed as: λ = c f. λ = c f. Example 5.1.

A wave packet has finite extend, and the photons will be found in regions where the wave packet does not have zero amplitude. But a wave packet must be build from harmonic waves with many different frequencies or wavelength. We therefore do not exactly know the energy E = hf and momentum p = h/ λ of the individual photons in the wave packet. O ...
