When a beam of light travels between two media having different refractive indices, the beam undergoes refraction and changes direction when it passes from the first medium into the second. To determine whether the light beam is composed of waves or particles, a model for each can be devised to explain the phenomenon (Figure 3).
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.
Nov 13, 2015 · Particle and Wave Refraction - When a beam of light travels between two media having different refractive indices, the beam undergoes refraction, and changes direction when it passes from the first medium into the second. According to the wave theory, a small portion of each angled wavefront should impact the second medium before the rest of ...
19 hours ago · The starting point was to scientifically distinguish between waves and particles. "You would describe an object as a particle if you can identify it as a point in space," Sapienza said ...
Aug 26, 2022 · Beams of light are often described as having wavelengths, yet they are also described as being composed of particles called photons. Light is unique in that it can be described as both a wave and a particle. However, for reasons that remain unknown, you can never observe light as both a wave and a particle at the same time.
Maxwell described light as a very special kind of wave -- one composed of electric and magnetic fields. 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.

Einstein’s explanation. Einstein had a great explanation for this peculiar observation. He hypothesised light is made of particles, and is in fact not a wave. He then linked the intensity of light to the number of photons in a beam, and the frequency of light to how much energy each photon carries. When more photons are shot at the metal ...
