X-rays are produced when highly energetic electrons interact with matter and convert their kinetic energy into electromagnetic radiation. The two unique mechanisms by which x-rays are produced are called the bremsstrahlung and characteristic processes.

What are x-rays solid state physics?
X-ray diffraction is coherent elastic scattering of x-rays by atoms or ions in a crystal. Because the wavelength of photons with energy of order 10 KeV is a little smaller than the spacing of atoms in solids, a crystal will act as a sort of diffraction grating for x-ray.
What are the 12 properties of x-rays?
- X-Rays are electromagnetic radiations having a wavelength between 10A to 0.01A.
- In Free Space, they travel in a straight line.
- Speed โ 1,86,000 miles/sec (same as that of visible light)
- X-rays Cannot be Focused on a Single Point.
- They are Invisible to Eye.
- Cannot be Heard.
- Cannot be Smelt.
What are the types of X-ray in physics?
There are two types of X-ray generated: characteristic radiation and bremsstrahlung radiation.

What frequency is X-ray?
X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10โ8 to 10โ12 metre and corresponding frequencies from about 1016 to 1020 hertz (Hz).
What are the five properties of X-rays?
- They have a shorter wavelength of the electromagnetic spectrum.
- Requires high voltage to produce X-Rays.
- They are used to capture the human skeleton defects.
- They travel in a straight line and do not carry an electric charge with them.
- They are capable of travelling in a vacuum.
What type of particle is X-ray?
X-rays and gamma rays are both types of high energy (high frequency) electromagnetic radiation. They are packets of energy that have no charge or mass (weight). These packets of energy are known as photons.
Does X-ray use AC or DC?
Both types of wall mounted intraoral x-rays in a dental office (whether it is a DC x-ray or an AC x-ray) are powered by basic AC electricity that comes from the wall.
What are the 3 types of X-rays?
- plain radiography, or plain x-ray.
- computed tomography, known as CT scanning.
- fluoroscopy โ which produces moving images of an organ.
- mammography โ an x-ray of the breasts.
- angiography โ an x-ray of the blood vessels.
What are 3 uses of X-rays?
- Check Symptoms in the Body. In the medical world, x-ray technology has many purposes.
- Diagnosing Injuries. A bone x-ray will use a small amount of ionizing radiation.
- Dental Check. A dentist will get images of your teeth with a dental x-ray.
- Mammography.
- Joint Changes and Arthritis.
What are 3 examples of X-rays?
- Abdominal x-ray.
- Barium x-ray.
- Bone x-ray.
- Chest x-ray.
- Dental x-ray.
- Extremity x-ray.
- Hand x-ray.
- Joint x-ray.
How do X-rays work simple explanation?
How X-rays work. X-rays are a type of radiation that can pass through the body. They can’t be seen by the naked eye and you can’t feel them. As they pass through the body, the energy from X-rays is absorbed at different rates by different parts of the body.
What is the basic principle of X-ray analysis?
Fundamental Principles of X-ray Powder Diffraction (XRD) X-ray diffraction is based on constructive interference of monochromatic X-rays and a crystalline sample. These X-rays are generated by a cathode ray tube, filtered to produce monochromatic radiation, collimated to concentrate, and directed toward the sample.
How does an X-ray work in detail?
An X-ray sends beams of radiation through your body. Radiation beams are invisible, and you can’t feel them. The beams pass through your body and create an image on an X-ray detector nearby. As the beams go through your body, bones, soft tissues and other structures absorb radiation in different ways.
How does an X-ray produce images?
X-rays are a form of electromagnetic radiation. They strike an object and, depending on the density of the object, some of the X-rays will be absorbed. X-rays that aren’t absorbed pass through the item being X-rayed, and they hit a photographic plate to give an image (although other methods can also be used).
What is Bragg’s law in physics?
What is Bragg’s Law? When the X-ray is incident onto a crystal surface, its angle of incidence, ฮธ, will reflect with the same angle of scattering, ฮธ. And, when the path difference, d is equal to a whole number, n, of wavelength ฮป, constructive interference will occur.
What are the three basic rules of radiography?
Three basic principles should be adhered to when dealing with radiation and making radiographs: โข Time โข Distance โข Shielding. These principles form the basis of a broader radiation safety concept called aLaRa (as Low as Reasonably achievable).
Why is Bragg’s law used?
The Bragg law is useful for measuring wavelengths and for determining the lattice spacings of crystals. To measure a particular wavelength, the radiation beam and the detector are both set at some arbitrary angle ฮธ. The angle is then modified until a strong signal is received.
What is the law of diffraction?
Diffraction can occur when any electromagnetic radiation interacts with a periodic structure. The repeat distance of the periodic structure must be about the same wavelength of the radiation. For example, light can be diffracted by a grating having scribed lines arranged on the order of the wavelength of light.
What is first order diffraction?
The first bright image to either side occurs when the difference in the pathlength of the light from adjacent slits of the grating is one wavelength, and it is called the “first order” diffraction maximum.
What are the five properties of xrays?
- They have a shorter wavelength of the electromagnetic spectrum.
- Requires high voltage to produce X-Rays.
- They are used to capture the human skeleton defects.
- They travel in a straight line and do not carry an electric charge with them.
- They are capable of travelling in a vacuum.
What is the rule of 2 in xray?
These rules are:- 1- Two views: One view is too few; 2- Two joints: Above and below the injured bone; 3- Two sides: Compare with the other normal side; 4- Two abnormalities:Find a second abnormality; 5- Two occasions: Compare the current x-ray with a previous one (especially in CXR); 6- Two visits: Repeat after an …
What is 10 day rule in radiography?
The “10 day rule” recommended that, in women of child-bearing potential, non-urgent x ray examinations that entailed pelvic irradiation should be restricted to the first 10 days of the menstrual cycle. Its rationale was to avoid irradiating a fetus before the mother realised that she was pregnant.
Why the angle is 2 theta in XRD?
Only those crystallites whose bragg planes are at an angle ฮธ with respect to the incident angle will diffract at an angle 2ฮธ with respect to the incident beam (or at an angle ฮธ with respect to the diffracting planes). So that is the reason, you always use 2ฮธ instead of ฮธ.
