components of an X-ray Tube? The x-ray tube consists of an electrode pair - a cathode and an anode. The cathode is a negatively charged heated filament made from tungsten. The anode is a positively charged flat disc‚ also made from tungsten. The electrode pair sits inside a glass vacuum tube‚ which is lined with lead for protection. 2) State the two interactions that occur in the X-ray tube to produce the x-ray beam Bermsstralhung interaction and Characteristic interaction. 3) The X-ray beam is attenuated

Technology is a wonderful thing. It has enabled us to do things that in the past were unimaginable to do. Technology these days has evolved a lot and it has changed our life for the better and for the worst. When I say for the better I mean that it has made us able to contact our beloved ones that are far away from home‚ made us able to use this technology to save our life when we are in danger‚ etc. But there are some bad things that this technology is doing to us.

solve problems and make life more enjoyable. Along with the benefits and praise‚ new technology always comes with concerns and potential detriments. Ray Bradbury’s “The Veldt” and the concept of self driving cars‚ both pose questions about the benefits and risks of new technology arising in the world. Numerous technologies that are presented in Ray Bradbury’s “The Veldt” have obvious benefits to everyday life. Machines in the house do many of the tedious tasks that one dreads on a daily basis.

Cathode ray tube is used for producing images‚ when an electron beam hits the surface made out of a phosphorescent‚ and the cathode ray tube is basically a vacuum tube. An example of a cathode ray tube is a computer desktop and the picture tubes in television are similar to the cathode ray tube in television. There are numerous components of cathode ray tube‚ which are the Electron gun‚ Anodes‚ Coil‚ Phosphor-coated screen‚ electronic beam and the spot through which the beam passes through. In a
