Radio waves and Microwaves Radio communications Radio waves are used to broadcast radio or television signals from transmitters‚ which are then converted into electrical signals with an aerial (which is made out of metal to absorb the radio waves) so you can hear and see them. When done so the aerial converts this wave into an electrical signal (because of the electromagnetic waves energy exciting particles in the aerial and causing them to oscillate/vibrate and thus create an electrical current)

Food irradiation: A food safety technology designed to eliminate disease-causing germs from foods. Treating food with ionizing radiation can kill bacteria and parasites that would otherwise cause foodborne disease. Similar technology is used to sterilize medical devices so they can be used in surgery or implanted without risk of infection. The effects of irradiation on the food and on animals and people eating irradiated food have been studied extensively. These studies show clearly that when irradiation

Title: Spectrophotometric analysis of a two-component mixture Aim: i. To prepare working standards of dichromate and permanganate ii. To measure the absorbance of the prepared working standards of dichromate and permanganate using a spectrophototometer iii. To determine the concentrations of permanganate in a mixture of unknown. Abstract: Working standards of dichromate and permanganate were prepared and absorbance for each found. This was done in order to plot

What is Radiology? “Radiology is the science dealing with x-rays and other high-energy radiation‚ especially the use of such radiation for the diagnosis and treatment of disease.” (Goergen). Most radiologists’ work in public or private hospitals or private radiology practices. Radiologists’ are there to help doctors determine the illness and how to treat it. “They do this by understanding when an imaging test may be needed to answer a doctor’s question about a symptom‚ disease‚ injury or treatment

(electromagnetic radiation) is utilised by organisms with photosynthetic abilities (pigments called chloroplasts) as a chemical energy source. Living chloroplasts can be readily isolated from live plant tissue and used to investigate photosynthesis (Lilley et al. 1975; Halliwell 1984). Photosynthetic organelles are Eukaryotic and are fundamental for the survival of not only the organisms themselves‚ but the entire ecosystem around them as well. After the electromagnetic radiation is completely absorbed
