- 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.
We might not have unified electrodynamics until 1865, but we've known light was a wave since the original double-slit experiment in 1801. Let's talk about di...

The way light behaves can seem very counterintuitive, and many physicists would agree with that, but once you figure out light waves it all starts to make mo...

- 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 ...
Jan 16, 2013 · In an approximate way, light is both a particle and a wave. But in an exact representation, light is neither a particle nor a wave, but is something more complex. As a metaphor, consider a cylindrical can of beans.

Light as Waves. Unlike water waves, light waves follow more complicated paths, and they don't need a medium to travel through. When the 19th century dawned, no real evidence had accumulated to prove the wave theory of light.
