In 1845, Michael Faraday showed that light and magnetism are linked. He passed a beam through glass inside a magnetic field and found that its polarization — the direction its waves wiggle — rotated.

Faraday waves, first observed by Michael Faraday in the 19th century, are standing waves that appear on the surface of a fluid when subjected to vertical oscillations. These waves characteristically ...

In 1845, physicist Michael Faraday provided the first direct evidence that electromagnetism and light are related. Now, it turns out that this connection is even stronger than Faraday imagined. In his ...
