- Light acts as a wave and can be described by a wavelength λ and a frequency ν.
17 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 ...
Light is called an 'electromagnetic wave' for historical reasons* in the following sense: It turned out that the effects of visible light and other radiation can be calculated using Maxwell's equations, which are also used to model the behaviour of electrically charged particles. This was an instant of a successful unification and it hasn't ...
Light behaves very strangely and confused scientists at first when they proved it behaved as both a wave and a particle. So, what’s actually going on? Learn more about the behaviour of light,...
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.

- Has Light Been Seen as Both?
Physicists debated for years whether light was a particle or wave. Isaac Newtonhad argued that light was composed of particles, yet other prominent scientists at the time argued that light was a wave. In 1801, physicist Thomas Young performed the double-slit experiment to determine whether or not light was a particle or wave. The double-slit experi...
Although most scientists had concluded that light was a wave and not a particle after the double-slit experiment, the story was not yet over. In the early 20th century, our understanding of the universe experienced one of its largest shifts in history due to the discovery of quantum mechanics. An entirely new area of physics opened up, and new theo...
The wave-particle duality of light is one of the strangest things about our universe. Although light has been seen as both particle and wave, it has never been seen as both at the same time. Every experiment devised to try and see both has resulted in one or the other. No matter how hard scientists try, light will simply change its behaviour from w...
Just what is the true nature of light? Is it a wave or perhaps a flow of extremely small particles? These questions have long puzzled scientists. Let's travel through history as we study the matter. Around 1700, Newton concluded that light was a group of particles (corpuscular theory).

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.
