Who first proved that light is a wave?
In 1801 a physicist in England, Thomas Young, performed an experiment that showed that light behaves as a wave. He passed a beam of light through two thin, parallel slits.
Who was the first to experiment with light?
The Italian physicist Galileo Galilee was among the first to try to measure the speed of light. In the early 17th century, he devised an experiment in which two people with covered lanterns stood a known distance apart.
Why did Huygens think light was a wave?
When a beam of light travels between two media having differing refractive indices, the beam undergoes refraction, and changes direction when it passes from the first medium into the second. Huygens believed that ether vibrated in the same direction as light, and formed a wave itself as it carried the light waves.
Who discovered the wave nature of electron?
Louis de Broglie
In 1924 Louis de Broglie introduced the idea that particles, such as electrons, could be described not only as particles but also as waves.
Who invented ripple tank?
Thomas Young
Thomas Young gave 91 lectures at the Royal Institution 1801-03. The musical phenomenon of beats, used to tune instruments, inspired Young to think that beams of light too might interfere. He invented the ripple tank to illustrate double slit interference, because water waves can be simply visualised.
Who showed that light is an electromagnetic wave?
This situation dramatically changed in the 1860s when the Scottish physicist James Clerk Maxwell, in a watershed theoretical treatment, unified the fields of electricity, magnetism, and optics. In his formulation of electromagnetism, Maxwell described light as a propagating wave of electric and magnetic fields.

Who studied light?
Born around a thousand years ago in present day Iraq, Al-Hasan Ibn al-Haytham (known in the West by the Latinised form of his first name, initially “Alhacen” and later “Alhazen”) was a pioneering scientific thinker who made important contributions to the understanding of vision, optics and light.
How did Einstein prove that light was a particle?
The explanation is very simple: the packets of energy are very tiny, so tiny that you don’t notice the bumps. Einstein thought “If energy comes in packets, then light could come in packets too!”, he called this packets photons and now everything made sense.
