X-Ray
Invented by Wilhelm Conrad Röntgen in 1895, X-ray imaging is used in hospitals to detect fractures to bone, as well as abnormalities to soft tissues.

What wave has a higher frequency microwave of X-ray?
An X-ray is a high frequency (high energy) electromagnetic wave. It is much higher in frequency than any broadcast wave. The only electromagnetic radiation with higher frequency (shorter wavelength) than the X-ray is the gamma ray.
X-Rays have more energy than gamma rays?
This statement is incorrect. Gamma rays have more energy than X-rays. Gamma rays are produced by nuclear reactions and have higher frequencies and energies than X-rays, which are produced by electron transitions within atoms.
materials that emit high-speed particles and energy-containing rays from the interior of their matter.
Who became famous because of his works on soft x-rays?
Casimiro del Rosario became famous on his work about Soft X Rays.
Del Rosario was the co-founder of the Bartol Research Foundation (Franklin Institute) in Philadelphia, an institution which did pioneering researches in physics.
X-rays are not deflected by magnetic fieldWhat does this indicate about yhe nature of rays?
That they have neither a negative or positive charge
Ultraviolet rays are potentially harmful to us due to their?
Ultraviolet rays are potentially harmful to us due to their intensity. This is what is known as the amplitude of the rays from the sun.
What does it mean when a guy tells you that he have x-ray vision?
Either your lying about something and he can see right through your lie OR he is imagining what you look like naked....good luck....
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.

Construction rays are imaginary lines used in geometric constructions to extend the direction of a line segment or angle without specifying a particular length. They help in visualizing relationships and intersections between geometric figures during the construction process. Often depicted as straight lines with an arrow at one end, construction rays facilitate the creation of points, angles, and shapes by guiding the drawing of additional elements.
The child had more organic material in her bones, which allows bones to be more flexible, while her grandmother's bones are extensively calcified, with little organic material, and are probably thin due to osteoporosis.
I hear if you put your video camera on "night vision" and put unused negative camera film over the lens, then you can see through certain substances. Through most outer were, but if you looking to see through under were it wont work because it wont go through cotton, but you can go to a swimming pool and see thru cloths there, but i don't think that is legal, you now if the cops catch you.
What is the difference between a homogenous and a heterogenous beam?
A homogenous beam contains photons of the same energy (monoenergetic)Because the photons all have the same energy, their interactions with materials (such as the absorber) are all the same resulting in uniform attenuation.
Heterogenous beams contain photons of different energies.
Because the photons have different energies, their interactions with materials (such as the absorber) are different resulting in non-uniform attenuation.
What do x-ray tech make in jacksonville fl?
The average income for an X-ray technician in Jacksonville, Florida is $35,000 per year. The average annual income for this position in Boulder, Colorado is $36,000.
Calculate the wavelength of an x ray with a frequency of 2.01018 Hz?
Electromagnetic radiation, which includes light and x-rays, travels at 299,792,458 metres per second
(c - a universal constant).
Speed, frequency and wavelength are related by the equation speed = frequency times wavelength.
The only problem with this question is that a frequency of 2.01018 Hz is not in the x-ray range
of frequencies. X-rays are found in the frequency range of 30 petaHertz to 30 exaHertz.
To put it another way, electromagnetic radiation with a frequency of 2.01018 Hz
has a wavelength of 149,137 kilometers (92,669 miles), and that's no X-ray.
Not nearly enough you need to worry about. You get more from a day at the beach or park.
Target Film Distance for a dental x-ray machine is generally 8" - 16", with the optimal distance being 12". This is the distance from the end of the PID (Position Indicating Device, the cone on the end of the machine) to the target INSIDE the machine, not the actual length of the PID. If your PID is 4", it is likely that the target inside the machine is a least 4 inches further, for a total TFD of 8". The amount of radiation intensity is inversely related to the distance - the less distance between the target and the film, the greater the amount of radiation; the greater distance, the less radiation. For the purpose of taking a dental radiograph, if you double your TFD, you need to increase the amount of time the film is exposed by the square of the original amount of time used. Time is measured in impulses, which equal 1/60 of a second. (A 15 impulse exposure is therefore only 1/4 of a second.) The amount of impulses used are kept really low so that the patient isn't exposed to much x-ray radiation at all.
