The original waves. In 1924, French physics doctoral student Louis de Broglie proposed that matter has a wave-like property. De Broglie was inspired by the discovery of wave-particle duality in light.

However, the wave theory of light predicted the opposite effect, that light should move slower in a substance of higher density, which was confirmed by 1850 with the work of Jean-Bernard-Léon ...

This represented a challenge to "wave theory", which had been advocated by 17th century Dutch astronomer Christiaan Huygens. . These theories were first communicated in 1678 to the Paris Academy ...

Light waves also have peaks and troughs and therefore ripple in a similar manner. In the wave theory of light, these oscillations are linked to two properties of light: intensity and frequency.

Thomas Young’s 1803 double-slit experiment producing interference seemed to have confirmed the wave theory of light. Thomas Young’s sketch of two-slit diffraction of waves, 1803.

The light we see is a tiny fraction of the electromagnetic spectrum. From radio waves to gamma rays, light delivers radio and TV and can destroy DNA or pass right through us.

To Newton's atomic theory of light, there was the very successful wave theory, which explained typical light behavior such as refraction (the change in the direction of propagation of light when ...

II. TO continue our study of visible light, that is, undulations ex tending from red to violet in the spectrum (which I am going to show you presently), I would first point out on this chart that ...
