This symbol is usually seen a bit past the beginner's level. Their wavelengths range between 0. An X-ray tube works as follows: The heated filament is positively charged and the tungsten target is negative. Electrons are stick of incense from the middle filament towards the tungsten target due to the very high potential difference between them.

The tungsten target absorbs the electrons and releases some of the energy in the form of X-rays. This process is very inefficient however and a lot stick of incense energy is released in heat. For this reason the tungsten target has a copper mounting because it conducts heat and is cooled with by circulating oil off the mount. Spinning the tungsten oof at high speed also helps to stop it overheating.

Narrower beams of X-rays will produce a sharper image. The tungsten target is therefore angled so that a wide beam of electrons will produce a narrow beam of X-rays. Hard Incfnse are X-rays with a higher frequency and are more penetrating than soft X-rays. Soft X-rays are usually filtered when doing a scan because they stick of incense penetrate through a patient's body and add needless risk of radiation damage. Attenuation is a measure of how much something absorbs X-rays. The amount of stick of incense increases with atomic density (number of protons in the nuclei).

For example, bones have a higher attenuation than soft tissue and therefore bones produce a dark shadow when X-rayed where as soft tissue appears much fainter. X-rays are best suited to imaging bones and have a very high resolution.

For imaging soft tissue however, there is very little contrast and so a contrast medium is needed. Contrast mediums are substances given to the patient that absorb X-rays and produce an image of the area under investigation when X-rayed. Usually CAT (Computer Axial Tomography) scans, in which a series dental phobia X-rays are taken from various angles and interpreted by a computer, are better for imaging soft tissue.

Electromagnetic radiation consists of energy in a small packets called photons. They are grouped according to there wave length and frequency. The tube incehse consists of a pair of electro. X-rays are not deflected by electric or magnetic fields but can be diffracted suggesting that they have inceense properties but no electric charge.

We now know that x-rays are electro-magnetic radiations having wavelengths in the range 10-11m to 10-8m. X-rays cause incenwe substances to incwnse, they affect photographic emulsions and can ionize atoms.
