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.
Mar 12, 2024 · Comparing the wavelength of visible light (a few hundred nm) to the size of an atom (on the order of 0.1 nm), explain why this poses a difficulty for reconciling the particle and wave theories. Can a white photon exist?
Currently light is thought of both as a wave and being made up of particles (photons), because as Robert mentioned in his answer, certain phenomena require modelling light as a wave to explain (interference, diffraction etc.), and others require photons (such as the photo-electric effect).
Nov 21, 2024 · Today, there's no doubt about the answer: Light is both a particle and a wave. But how did scientists reach this mind-bending conclusion? The starting point was to scientifically distinguish...

- History of The Double-Slit Experiment
Christian Huygens was the first to describe light as traveling in waves whilst Isaac Newton thought light was composed of tiny particles according to Las Cumbres Observatory. But who is right? British polymath Thomas Young designed the double-slit experiment to put these theories to the test. To appreciate the truly bizarre nature of the double-spl...
The smallest constituent of light is subatomic particles called photons. By using photons instead of grains of sand we can carry out the double-slit experiment on an atomic scale. If you block off one of the slits, so it is just a single-slit experiment, and fire photons through to the sensor screen, the photons will appear as pinprick points on th...
The first version of the double-slit experiment was carried out in 1801 by British polymath Thomas Young, according to the American Physical Society(APS). His experiment demonstrated the interference of light waves and provided evidence that light was a wave, not a particle. Young also used data from his experiments to calculate the wavelengths of ...
Dec 12, 2013 · In the 19th century scientists decided that light must be a wave, but after witnessing light demonstrating particlelike behavior, Albert Einstein proposed that light can indeed be described...
Is light a wave or a particle? How is it created? And why can’t humans see the whole spectrum of light? All your questions answered.
