wanted to do I would go find food supplies and supplies to build a shelter‚ I would gather a flashlight and some batteries; all the essentials. I would attempt to build a shelter and I would get hide all my food in a place that it would not get radiation poisoning. I would get games- even though you wouldn’t think to play games while you’re getting bombed- I’d also take all my favourite things I own and bring them with me into my shelter‚ also I would gather everyone I love to come and stay in this

in radar help to decide the range‚ angle‚ or speed of objects. Radio waves have the longest wavelength‚ smallest frequency‚ and the least energy of all electromagnetic waves. These waves are a type of electromagnetic radiation‚ which additionally include microwaves‚ infrared radiation‚ x-rays‚ and gamma rays. Other important uses of radio waves are for television‚ cellphones‚ and

radioisotopes has increased our knowledge of biological processes and chemical reactions in humans and plants. New technologies: Geiger counter and Autoradiography. A Geiger counter is a type of particle detector that measures ionizing radiation. It is used as a handheld radiation survey instrument. Autoradiography is a technique used to trace the movements of certain substances around plants. The movement of the radioisotope can be traced by taking an autoradiograph. An autoradiograph is produced when

The Photoelectric Effect Definition: It is the emission of electrons from a metal surface under the illumination of a suitable radiation. The photoelectric effect is the phenomenon whereby electrons are emitted from a surface (usually metallic) upon the exposure to and absorption of electromagnetic radiation‚ such as visible light‚ that is above the threshold frequency. This is because electrons cannot get enough energy to overcome their atomic bonding. The photoelectric effect furthered wave

Nasal Cancers Tumors established within an individual’s nose can be either malignant (cancerous) or benign (non-cancerous). In all cases‚ those affected with nasal cancer frequently go through an advanced surgical procedure to confiscate the cancerous tissue/s. This is subsequently followed by a reconstructive rhinoplasty to help the person restore or improve the former shape of the nose. This is because nasal cancers often leave large defects in the nose. Proper reconstruction should aim not just

reflection from the ionosphere. Sky waves: a radio wave that is reflected back to earth by the ionosphere or a communications satellite; permits transmission around the curve of the earth’s surface Line of propagation: is the electro-magnetic radiation or acoustic wave propagation. Electromagnetic transmission light travels in a straight line. The rays or waves can be diffracted‚ refracted‚ reflected‚ or absorbed by atmosphere and obstructions with material and generally cannot travel over the

problem remained. There was one experiment conducted by Hertz‚ the photoelectric effect‚ which could not be explained by considering light to be a wave. Hertz observed that when certain metals are illuminated by light or other electromagnetic radiation‚ they lose electrons. Suppose we set up an electric circuit. In this circuit the negative terminal of a battery has been connected to a piece of sodium metal. The positive terminal of the battery is connected through a meter that measures electric

A good example of black body radiation is the heat inside a stove‚ electromagnetic radiation light and heat exist in a form of standing waves‚ waves like the vibration of a guitar string is attached in both ends. The ends of the standing waves do not move‚ the are attached to the side of the stove‚ and many waves

The cancer i chose to write about was bladder cancer. I’m not really sure why i chose this cancer but i find it cool that you can get cancer in all different places. Nobody knows the main cause of bladder cancer. Some things that may cause cancer is chronic bladder inflammation‚ chemical exposure or smoking. I find it very weird that smoking could affect your bladder or even drinking caffeine can. Cystoscopy is the main diagnostic test for bladder cancer‚ you can also get a bladder biopsy which
