Cathode Ray
A cathode ray is a stream of electrons emitted from the cathode in a vacuum tube, fundamental to early electronic devices for displaying images and signals. This phenomenon not only revolutionized visual technology but also paved the way for modern screens, though it's largely obsolete today due to advancements like LCDs.
Did you know?
Cathode rays were instrumental in Wilhelm Röntgen's 1895 discovery of X-rays, which he stumbled upon while experimenting with these electron beams, leading to the first medical X-ray image of his wife's hand and revolutionizing diagnostics. This breakthrough earned Röntgen the first Nobel Prize in Physics in 1901, and it all started from what was initially seen as mere laboratory curiosity.
