HUM three hundred , history methods of scientific discipline9 . Why atomic number 18 X-rays employ for checkup diagnosis ? What contrastive wavelengths of electro magnetic shaft argon apply in medicineTo make taboo the questions would mean defining the characteristics of an roentgenogram which makes it an essential tool in the knit stitch of medicine . X-rays be highly keen electromagnetic waves with extremely short wavelengths make use ofd in the medical vault of heaven for medical symptomatic stick out X-ray burns bowl overing through matter undergo the processes of acculturation scatter , and fluorescence . Its electromagnetic radiation passes through the tissues of the frame get out gives a very distinctive outline of the tog out up . Photons argon normally blocked by dull structures like bones and r esults to its white appearance on characterisation . X-rays has nondeflected electric and magnetic field with no charge (Sharma et al 2005 . Its electromagnetic wavelengths are highly penetrating and can pass through cloudy tissues and solids towards light . It has the cleverness to cause fluorescence in substances and produce a photographic plate . It has shorter wavelength compared from substances of high atomic weights that makes it more penetrating . This has been conveniently used by physicians to locate foreign objects inner(a) the human physical structure in a nonintrusive proficiency without the use of surgery . X-rays are also used to appraise bone integrity and joint diss of the human body . X-rays are good in revealing the conditions of the bones or some(prenominal) abnormalities of the bones like fractures without having to undergo surgery . X-rays reacts with photographic films after(prenominal) passage through body tissues which absorbs the electromagnetic en ergy at different rates producing contrastin! g pictures of the structures inside the body on a photographic plateOther wavelength used in the medical field is unhearable waves or supersonic waves which are noted as very small wavelengths compared to audible sound .

echography is usually defined as the sound waves beyond human comprehend for which its use in medical diagnosis is only southward to x-rays . An ultrasound beam experiences both refraction and reflection which penetrates and interacts with the body making easily measurable transit times that permits radar-like pulse-echo methods . Ultrasound produces images from stationary and miserable tissues . Other known medical diagnostic preferences are magnetic resonance imagin g , fluoroscopy , and CT scan . Lasers have its mix of applications in the medical field where there is a favorable interaction amid the human tissue and the laser radiation Radiation wavelength , the tissues ability to absorb this wavelength and the delivered power on the tempered area determines the achiever of this interaction . Science and physics has feature its forces in an grounds to develop powerful interventions in the field of medicineReferencesSharma , H .C . et al (2005 . Comprehensive physics for engineers .
