An X-Ray is a type of photograph usually taken by the doctor during a health check. This X-ray was discovered by WILLIAM C.ROENTGEN (1845-1923), born in Prussian Lennep. He accidentally discovered the strange beam of light while experimenting with electricity. He soon discovered that this beam of light has the properties to pierce through any object and named it "X-radiation".
So why did he name them X-rays?... "X" implies the unknown. In other words, X-radiation is "an unknown beam of light". Though he discovered it, Roentgen felt that there were still many characteristics he had not yet found out about this beam. And hence named them "X-Rays".He took the world's first X-ray using his wife's hand.
Sometimes X-rays are also called as Roentgen rays in honor of the man who discovered them.He received the first Nobel prize for physics in 1901.He also found that X-rays had four main characteristics.
- The heavier the wave is, the harder it is for it to pass through.
- Like photograph, X-rays can be exposed on a dry, black photographic plate.
- X-rays can make things glow.
- When X-rays run into something, they scatter light.
