visible light source. A light source such as incandescent light bulb utilizing hot metal filaments is consisted of a continuous distribution of lights with a range of wavelengths, hence forming a white light. On the other hand, light produced from a mercury lamp and helium lamp contains only several discrete wavelength components. A number of methods can be adopted to measure the separated wavelength components. However, for this experiment, we will be focusing on using diffraction grating in which

and Filipinos have to work. Children are forced to work in gold mines mainly because their families are poor and need the money. Most families are unaware of the health issues from mercury and how dangerous the heavy machinery can be. Children’s health is the issue because they are exposed to toxic gases such as mercury is a very toxic metal and can lead to physical disorders when inhaled or absorbed by skin. The children do not wear any protective clothing while working in the mines and do not use

Dental amalgam, a restorative material that contains a mixture of mercury, silver, copper and tin, has been controversial throughout the years questioning its safety. The main concern is the level of mercury and its potential toxicity (Osbourne). By eliminating it from this office and becoming “amalgam-free”, may not be the best decision for our patients. Amalgam has many advantages over other restorative materials and should remain an option for patients when having restorative work done. Amalgam
