location of the elements in the diffraction grating that produced them. Conversely‚ if we know the structure of the grating‚ we can deduce properties about the incident light‚ in particular its wavelength. This will be our task‚ in this first optics lab exercise. The analysis of diffraction patterns is used extensively in the sciences to provide information about the microscopic structure of molecules‚ atoms‚ and nuclei. In addition to various forms of light (gamma rays‚ x-rays‚ visible light‚ infra-red

1. Describe the function of the following pieces of safety equipment and how each might be used: a. Eye wash- To be used in the event of a chemical splash to the eyes. Should be used to flood the eyes for at least 15-30 minutes with water‚ flooding from the eye outward. b. Fire Blanket- To be used in the case of a small fire. Would be tossed onto flames to suffocate the flow of oxygen. c. Shower- Safety showers are designed to flood your body with water in the event of a fire or chemical spill

Physics (Thorpe Park Trip) Report: On Monday 8th October our physics class went on a physics trip to Thorpe Park to look at the different ways in which a roller coast works. This report will be looking at the G forces acting on rides‚ the launching systems and breaking systems. The particular rollercoaster which I have picked to look into more detail in is “Stealth” which is located in Thorpe Park. Stealth: Stealth was originally designed by Werner Stengel. Stealth reaches a height of 205 feet

change in Gatineau Park‚ Old Chelsea‚ were studied quantitatively. The relations between different successional stages of plant communities and abiotic factors were descried. To test these‚ we went to the fields‚ and worked on two transect in groups of 4. We counted the trees and measured the diameter at breast height (dbh) for tree with a dbh value greater than 2cm. The dbh measurements (cm)‚ percentage of fern cover and percentage of bare ground were recorded and used to perform statistical analysis
