uses of gamma rays

Formation of Image by a Plane Mirror - Ray Diagrams - The following rays are usually considered while constructing ray diagrams: A ray of light incident on a plane mirror at 90 degree gets reflected from the mirror along the same path. A ray of ligh..

1. It is used for water and gas pipes. 2. It is used for the plates of lead-acid accumulators (batteries). 3. As a screen from radioactive rays. 4. In alloys such as type metal, solder, etc. 5. In bullets. 6. To prepare lead tetraethyl, (C 2 H 4 )Pb which is used..

It is used in spectacles for correcting myopia. along with convex lens it is used to overcome defects like chromatic aberration and spherical aberration (the failure of rays to converge at one focus because of a defect in a lens or mirror..

The line containing any two points in a plane lies wholly in that plane. An angle has only one and only one bisector. Through any point outside a line, one and only one perpendicular can be drawn to the given line. A segment has one and only one mid point. Linear pair postulate: If a ray..

Optical Centre - It is the centre of a lens. It is denoted by the letter O. A ray of light passing through the optical centre of a lens does not suffer any deviation. It is also referred to as optic cent..

As the wave is refracted, it is bent down gradually rather than sharply. However, below the ionised layer, the incident and refracted rays follow paths that are exactly the same as they would have been if reflection had taken place from a surface located at a greater height, called the vi..

Radio isotopes are used in detection of diseases and also in radio therapy: The rays from radium is used in the treatment of skin diseases. Radiation from Co 6 0 ( - rays) is used to diagnose and treat thyroid disorders. Radio iodine (I ..

PET is a sophisticated version of radio isotope scanning. The principle behind PET scanning is as follows. Short - lived radio isotopes such as 1 1 C, 1 3 N or 1 5 O are produced and incorporated into a solution (of glucose) that can be injected into the body. As the radio isotope circulates throug..

. When a nucleus emits radiation it is said to decay. Rays from radioactive isotopes are dangerous to living things but are also useful in variety of ways. Exposure to large amounts of radiation is harmful to health. All radioactive materials should always be handled with care a..

While all electromagnetic waves travel at the same speed (i.e., velocity 'c' is constant), the type of their radiation differs in the duration of wavelength and consequently their frequencies. An electromagnetic radiation with a long wavelength will have a low frequency and vice versa. 'The arra..
