- 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 ...
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.
When we say light is a wave, it isn't exactly the same as an ocean wave. They are both called "waves", but they are not really the same thing. A wave in the ocean is just a bunch of particles moved together in a uniform shape that we call a wave.
Around the same time, there were other scholars who thought that light might instead be a wave (wave theory). Light travels in a straight line, and therefore it was only natural for Newton to think of it as extremely small particles that are emitted by a light source and reflected by objects.
Greek scientists from the ancient Pythagorean discipline postulated that every visible object emits a steady stream of particles, while Aristotle concluded that light travels in a manner similar to waves in the ocean.
