what is the difference between bremsstrahlung and characteristic x-rays?
478681
Characteristic radiation produces a line spectrum with several discrete energies, whereas Bremsstrahlung produces a continuous spectrum of photon energies over a specific range.

Gamma rays are the highest energy EM radiation and typically have energies greater than 100 keV, frequencies greater than 1019 Hz, and wavelengths less than 10 picometers. ... Gamma rays have characteristics identical to X-rays of the same frequency—they differ only in source.

What is the one fundamental difference between X rays and radio waves? The wavelengths of X rays and radio waves are very different.

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).

The difference between the two comes down to definitions of the two words. An x ray is a photon of energy. This is what is exposing the patient for the final image. ... A radiograph is the resultant image after a patient or object is exposed to x rays.

Less radiation needed to produce the same quality image as film (digital X-rays gives 70% less exposure to radiation than conventional X-rays). Digital archivinga  the ability to store images on a computer. Grey-scale of digital X-rays offers 256 shades of grey versus 16-25 shades in conventional radiography.

Radiography is the imaging of body structures, or parts of the body, using X-rays. X-rays are a form of radiation (X-radiation) similar to visible light, radio waves and microwaves. ... Plain X-rays are the simplest medical images created through X-radiation.

X rays are electromagnetic radiation that differentially penetrates structures within the body and creates images of these structures on photographic film or a fluorescent screen. These images are called diagnostic x rays.

Gamma-ray photons have the highest energy in the EMR spectrum and their waves have the shortest wavelength. Scientists measure the energy of photons in electron volts (eV). X-ray photons have energies in the range 100 eV to 100,000 eV (or 100 keV). Gamma-ray photons generally have energies greater than 100 keV.

X-Rays. X-rays are electromagnetic waves with wavelengths in the range of 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×1016 Hz to 3×1019 Hz) and energies in the range 100 eV to 100 keV. They are shorter in wavelength than UV rays and longer than gamma rays.

X-rays. X-rays are high-frequency, and thus high-energy, electromagnetic radiation. They have wavelengths ranging from 0.01 to 10 nanometres, and thus frequencies from 3×1019 to 3×1016 Hz. They are found to reside between ultraviolet radiation and gamma rays on the electromagnetic spectrum. The electromagnetic spectrum.

Two key points to remember about the characteristics of radiation are that X- and gamma rays are not bits of matter, they are electromagnetic wave forms possessing no charge and no mass, and they can be characterized by frequency, wavelength, and velocity.

In common scientific usage, high-energy particles with intrinsic mass are known as "cosmic" rays, while photons, which are quanta of electromagnetic radiation (and so have no intrinsic mass) are known by their common names, such as gamma rays or X-rays, depending on their photon energy.

X-rays work just like visible light (in fact they're just a higher energy form of light) in that they are able to pass straight through some materials (just like light passes through glass) but not through others (just like light doesn't get through walls).

Everything that happens in radiology uses energy of one kind or another. A common chest x-ray uses a higher energy form of electromagnetic radiation. ... Ultrasound uses sound wave energy to create images while nuclear medicine uses radioactive substances put into the body to create images and treat diseases.
