uses of gamma rays

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 light falling on a plane mirror at any angle gets reflected from..

It is the center of a lens. It is denoted by the letter O. A ray of light passing through the optical center of a lens does not suffer any deviation. It is also referred to as optic cente..

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)..

Optical Center - It is the center of a lens. It is denoted by the letter O. A ray of light passing through the optical center 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 ..

Important Terms Used in the Study of Sky Wave Propagation - 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..

Radioactive phosphorus (P 3 2 ) is used in the study of metabolism of plants. Radioactive sulphur (S 3 5 ) helps to study advantages and disadvantages of fungicides. Pests and insects on crops can be killed by - radiations., - rays are used for preser..

Positron Emission Tomography (PET) - 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. A..

>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 an..

The rays that deflected towards the negative plate consist of positively charged particles and these were called alpha rays. The rays, which deflected towards the positive plate, consist of negatively charged particles and these rays were known as the be..
