Apr 24, 2017 · A Ray of Light. When an electromagnetic source generates light, the light travels outward as a series of concentric spheres spaced in accordance with the vibration of the source. Light always takes the shortest path between a source and destination. A line drawn from the source to the destination, perpendicular to the wave-fronts, is called a ray.
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 ...
In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. [4][5] In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum, and polarization.
Meanwhile, when we think about light propagating as waves, these are waves of electromagnetic radiation. Other examples of electromagnetic radiation include X-rays and ultraviolet radiation. It’s worth remembering light — regardless of whether it’s behaving like a wave or particles — will always travel at roughly 300,000 kilometres per second.
Light rays and ray diagrams. Light travels in a straight line. When drawing a light ray: Use a ruler and a sharp pencil to draw a straight line. Add an arrow to show the direction the light is ...
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 light particle conceived by Einstein is called a photon. The main point of his light quantum theory is the idea that light's energy is related to its oscillation frequency (known as frequency in the case of radio waves). Oscillation frequency is equal to the speed of light divided by its wavelength. Photons have energy equal to their ...
