What did jj thomas discover?
J.J.Thomas discovered that atoms have negatively charged particles called electrons. He discovered this using the Cathode Ray. The cathode ray is a beam of electrons emitted by the cathode of an electrical discharged tube.
What year was the first X-ray machine made and by whom?
The first x-ray was taken in 1895 by Wilhelm Conrad Rontgen. He used an enclosed discharge tube of a cathode ray in a sealed, black carton so that no light would reach the tube, and but a paper plate covered in barium platinocyanide on ones side. The first x-ray was taken of his wife's hand.
What was JJ Thompson working with when he discovered the cathode rays?
Electrons.
What following piece of equipment was used by jj Thomson to find electrons?
JJ Thomson discovered electrons using a cathode ray tube.
Who discovered negatively charged electrons using a cathode ray tube?
JJ Thomson.
Who discovered rays?
Wilhelm Roentgen Wilhelm Roentgen, Professor of Physics in Wurzburg, Bavaria, discovered X-rays in 1895—accidentally—while testing whether cathode rays could pass through glass
What are the contributions of Wilhelm rontgen?
Wilhelm Conrad Roentgen discovered X-rays while experimenting with cathode ray tubes. In recognition of his feat, IUPAC named a new element, Roentgenium, after him.

How do WK Roentgen and florescence relate?
Wilhelm Roentgen was conducting an experiment and found that invisible cathode rays produced a fluorescent effect under certain circumstances. This led him to produce what we know today as X-rays.
Inventor of the cathode ray tube?
roentgen
Contribution of Wilhelm roentgen?
Wilhelm Conrad Roentgen (1845 - 1923) discovered X rays, for which he received the first Nobel Prize for physics in 1901. He observed that barium platinocyanide crystals across the room fluoresced whenever he turned on a Crooke's, or cathode-ray discharge, tube, even when the tube was shielded by thin metal sheets. Roentgen correctly hypothesized that a previously unknown form of radiation of very short wavelength was involved, and that these X rays (a term he coined) caused the crystals to glow. He later demonstrated the metallurgical and medical use of X rays which later brough a revolution the medical science..
Why was the X-ray machine made?
Wilhelm Conrad Rontgen discovered the X-Ray by accident when he was experimenting with cathode rays in vacuum tubes.
How did Wilhelm Rontgen contribute to the development of nuclear energy?
He discovered x-rays were emitted by cathode ray tubes (CRTs) under certain conditions.
Who invented x rays?
On November 8th, 1895, German scientist Wilhelm Roentgen was conducting experiments in his laboratory on the effects of cathode rays. Specifically he was observing the effect of passing an electrical discharge through gases at a low pressure. While doing so, Roentgen noticed something that earlier studies had not picked up. While passing current through the cathode ray, rays were given off that passed through every day materials such as wood, paper and aluminium. Roentgen further observed that a surface that he had coated with barium platinocyanide and which was placed outside of the cathode discharge tube would give off light despite the fact that it was hidden from the light of the discharge. The conclusions that Roentgen came to were ground breaking: a previously unknown type of radiation had passed through the air and lit up the screen. Roentgen's discovery was to open up an exciting field for doctors. It was now possible to use this new form of radiation in the study of the human body. Broken bones, for example, could now be looked at by using the rays to see straight through flesh. To underscore the unknown nature of his new discovery, Roentgen decided to call them x-rays. Roentgen spent the next two months carefully investigating the properties of the new radiation he had discovered. He then made a formal correspondence to the University Physical-Medical Society informing them of his discovery. In 1901 he was to receive the Nobel Prize for his work. It was the crowning achievement of a career that saw him rise from obscurity. Wilhelm Roentgen was born on March 27, 1845 in Lennop, a small town in Germany's Rhineland. As a young boy, Wilhelm was drawn to nature. He loved to experiment and to pull things apart. His school years, however, were quite troublesome. He was of average academic ability but had a knack for causing trouble. Refusing to bow down to the authority of his teachers, he was eventually expelled from school without any qualifications. This was a problem to young Wilhelm because he had set his sights on an academic career in the sciences. In his late teens Wilhelm decided to give education a more serious effort. He enrolled at the Poly-Technical Institute in Zurich. Now showing the academic discipline that was earlier lacking, he soon earned a degree in Mechanical Engineering. Having done so, however, he was at somewhat of a loose end. He didn't yet know where he wanted to go with this qualification. It was at this time that Roentgen met the woman who was to be his wife, Anna Ludwig.
What is x-ray production?
X-Rays were discovered by Wilhelm Conrad Roentgen on November 8, 1895. While working with cathode rays, Roentgen noticed a barium plantinocyanide screen glowing in his laboratory. He activated the Crookes tube in complete darkness with the tube covered and noticed the screens continued to glow. These unknown rays that caused screens to glow were called x-rays. He placed different materials, including his wife's hand, in the path of the x-rays and noticed that some objects were easily penetrated and others were not.
Who discovered anode and cathode rays?
Cathode rays were discovered by JJ Thomson and carry a negative charge Anode rays were discovered by Goldstein and carry a positive charge.
Where was the x-ray machine invented?
Germany. In late 1895, a German physicist, W.C. Roentgen was working with a cathode ray tube in his laboratory. this tube created a light which he discovered can emit through solids an outlines onto a sheet of paper 1223343455666my milkshake
