What is the shortest wavelength radiation present in an X-ray machine with a potential difference of operation is 50,000 V?
I had the numbers and equations but said he is totally over my head.
The speed of the electron hitting the anode is a function of tube voltage. As the voltage (V) varies, so will the energy of the electron as it strikes the anode. This contributes to the "white" or continuous spectrum of wavelengths emitted by X-ray tube X. The shortest wavelength emitted is a function of the maximum voltage applied on the tube and is given by the Duane-Hunt law which states that "the wavelength of greatest intensity is approximately twice that of most short wavelength (SWL) issued ".The minimum wavelength generated is given by the following equation:
1243/Vtube = SWL (SWL in nanometers)
Gives 50'000V wavelengths shorter than 0.

On the advantages of the machine, Idris said that the X-ray machine is faster and has less effect of radiation. "It does not require consumables such as chemicals, dark room. He acquired x-ray image easier to handle and process. It is faster than the procedure of non-processing time of the film is required. And the operation of the equipment is cheaper than the old traditional method."
Suggesting that the machinery would soon be linked by Internet to other hospitals and offices, he said Lagosians aged 0-12 years and adults over 60 years would be privileged to enjoy the services of the machine without costs in the context of health services the government.
During a demonstration, Consultant Radiologist, Prof. Awosanya Gbolahan told the machine to function in the process easy and convenient as any classic exhibition can be done on a patient while standing, sitting or lying (lying) position.It is battery operated and can be used in areas where food is not effective or not available.

The bad reputation has passed the x-ray machine that tells the elite during the Apollo 10 capsule align Stephenson and sky-rocket.
Not quite 10,000 people named as the winner for free for making the most sense to the ancient, contemporary and future.
Ten of the most important objects in the method, engineering, technology and remedy were to vote.
50,000 votes were closely as in the inventory of the Technical Museum.
The first three positions have been filled with inventions and medical breakthroughs, the X-ray machine being followed by the discovery of penicillin and dead ringer for the Helix DNA form.
X-rays provided the potential first look inside the Association of someone without sardonic available - a huge move forward medical.
"Patients Laying almost empty"
The separate machine x-ray in doubt - the machine Reynolds Museum Making the Gallery The Current public - was a "do-it-youself" attempt by a father and son who were so inspired by the advice of the finding that X - ray that they start building gear in their own place.
THE RESULTS 1st slot - X-ray machine 2nd grade - 3rd spot Penicillin - DNA double helix against 4th - Apollo 10 Capsule Part 5 - Rise V2 quickly Appliance 6th Group - Stephenson's Take off successfully 7th - 8th Fly Ace Computer lost humble - Steam Mechanism 9th back in the world - Mock-up Model T Ford home 10th - Thrilling Telegraph
Museum curator Katie Maggs said: "It is very inspiring for budding scientists to learn a gadget now said the most critical in the distribution could be developed by the inventors serious mess."
Professor Andy Adam, President of the College of Radiologists Majestic was pleased to learn that the consequence.
He said the X-ray machine had revolutionized the rule and that medical technology had Abet today so that we reach the age of unwavering "pellucid"....
