PHYSICS: APPARATUS, 1879.
A Crookes tube in which a strip of platinum (b) is made red hot by the passage of current between the bowl-shaped cathode (a) and an anode (D). In a partial vacuum, this current was said to consist of cathode rays

EDITORS COMMENTS
This vintage photograph captures a significant moment in the history of physics. Taken in 1879, it showcases an apparatus known as a Crookes tube, invented by English scientist Sir William Crookes. The central focus of the image is a strip of platinum (b) that glows red hot due to the passage of electric current between the bowl-shaped cathode (a) and anode (D). This experiment took place within a partial vacuum, revealing what was then referred to as "cathode rays". The invention of the Crookes tube marked a groundbreaking discovery in science. It provided evidence for the existence of cathode rays and their behavior under different conditions. These findings contributed greatly to our understanding of electricity and paved the way for future advancements in physics. In this print from Granger Art on Demand, we are reminded of how far scientific knowledge has come since its capture over 140 years ago. It serves as a testament to Sir William Crookes' ingenuity and his contributions to the field.
