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)

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

The article by the various authors listed above concentrated on the various techniques that are used to locate and then to excavate these sites. They list and discuss the various techniques that they use. These vary from side-scanning to locate the sites to high resolution video to see how the site appears and the various locations

increases. Absorbance is directly proportional to the path length‚ b‚ and the concentration‚ c‚ of the absorbing species. Beer’s Law states that A = ebc‚ where e is a constant of proportionality‚ called the absorptivity. Different molecules absorb radiation of different wavelengths. An absorption spectrum will show a number of absorption bands corresponding to structural groups within the molecule. In this experiment wavelength range between 400-650nm is used in order to detect in the visible range

ground state‚ several distinct energy emissions occur. Electrons may become excited when a sample of matter is heated or subjected to an electrical current. The energy that electrons emit when returning to the ground state is electromagnetic radiation‚ or EMR. Sometimes the EMR can be seen as visible light. In 1900‚ Max Planck studied visible emissions from hot glowing solids. He proposed that light was emitted in packets of energy called quanta and that the energy of each packet was proportional

(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
