- But all behavior of light can be explained by combining the two models: light behaves like particles and light behaves like 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.

- Light Is A Wave … and A Particle
- Matter Is A Wave … and A Particle
At first glance (and even at deeper glances), waves and particles are very different. A particle is, as best as I can put it, a thing. It's a small, single, finite object. You can hold a particle in your hand. You can throw a particle at someone else and watch it bounce off of them. It's localized. You can point to a particle and say, "Look, the pa...
The problems with this approach started with light itself. In the early 1800s, the English scientist Thomas Young played some games with light by shining some beams through two narrow openings onto a screen behind them. What he found was a classic interference pattern with stripes of varying intensity on the screen. This is exactly what water waves...
In the 1920s, a young physicist named Louis de Broglie made a radical suggestion: Since light has energy, momentum and a wavelength, and matterhas energy and momentum, maybe matter has a wavelength, too. That's something that's easy to say but hard to wrap your head around. What does it mean for matter to have a wavelength? Or was de Broglie just h...
Mar 23, 2022 · It demonstrates that matter and energy (such as light) can exhibit both wave and particle characteristics — known as the particle-wave duality of matter — depending on the scenario, according to...
Mar 12, 2024 · 13.2.3 Wave-particle duality. How can light be both a particle and a wave? We are now ready to resolve this seeming contradiction. Often in science when something seems paradoxical, it's because we (1) don't define our terms carefully, or (2) don't test our ideas against any specific real-world situation. Let's define particles and waves as ...
Dec 12, 2013 · How could something as simple as light be made of particles? Physicists describe light as both a particle. and. a wave. In fact, light's wavelike behavior is responsible for a lot of its cool...
May 24, 2024 · We know that light is a wave based on how it behaves – it exhibits the same properties of other waves we have examined – it interferes with itself, it follows an inverse-square law for intensity (brightness), and so on.

May 17, 2016 · An excellent comparison of the wave and particle theories involves the differences that occur when light is reflected from a smooth, specular surface, such as a mirror. This interactive tutorial explores how particles and waves behave when reflected from a smooth surface.
