- No. The particles again make a wave-like interference pattern on the sensor screen. When the detector is switched off the photons make a wave-like interference pattern on the sensor screen. (Image credit: Future) The atoms appear to act like waves when you're not watching them, but as particles when you are.

Mar 12, 2024 · If, on the other hand, light was only a wave and not a particle, we would get the same kind of diffraction pattern that would happen with a water wave, k. There would be no discrete dots in the photo, only a diffraction pattern that shaded smoothly between light and dark.

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...
16 hours ago · According to Sapienza, this isn't the right question to be asking. "Light is not sometimes a particle and sometimes a wave," he said. "It is always both a wave and a particle. It's just that we ...
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,...
If light is a particle, then why does it refract when travelling from one medium to another? And if light is a wave, then why does it dislodge electrons ? But all behavior of light can be explained by combining the two models: light behaves like particles and light behaves like waves.
Jan 16, 2013 · Light sometimes acts like a wave and sometimes acts like a particle, depending on the situation. This only makes sense if you accept that light is something more complex; something that from a certain perspective looks wave-like and from another perspective looks particle-like.

Light as a Particle. Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Photons carry a fixed amount of energy but have no mass. The energy of a photon depends on its wavelength: longer wavelength photons have less energy and shorter wavelength photons have more.
