The headwaters of the Doce River rise in the southeast-east area (SE-E) of the Iron Quadrangle‚ located in south-central portion (C-S) of the state of Minas Gerais (Figure 1). The Iron Quadrangle is historically known as a rich auri-ferriferous province and is a classic region of the world Precambrian geology (Dorr‚ 1959). Its designation results from the area’s planimetric features‚ with a surface area of around 7‚000 km2‚ comprising the most important iron mines of Minas Gerais (Barbosa‚ 1968)

Chapter 14 Outline I. Refraction of Light A. Refraction is the bending of light at the boundary of two media. 1. It is caused by differences in the way light travels in the two media a) Light changes speed unequally. (1) One side of the light becomes slower/faster 2. If light is perpendicular to the new medium‚ light will not refract a) If the media have the same index of refraction‚ light will not refract B. Index of Refraction 1. How well light travels through a medium is measured by

1 in vapour state sulphur partly exists as S2 molecule which has 2 unpaired electrons in the antibondind pi orbitals jus lyk oxygen and thus exhibits paramagnetism. 2 An interhalogen compound is a molecule whose atom contains two or more different halogen atoms (fluorine‚ chlorine‚ bromine‚ iodine or astatine). Most interhalogen compounds known are binary (composed of only two distinct elements). Their formulas are generally XYn‚ where n = 1‚ 3‚ 5 or 7‚ and X is the less electronegative

Objective The objective of this experiment was to find the focal length of two converging lenses separately and also to find the focal length of combination of two converging lenses. Another objective was to study the image formed by a converging lens plus diverging lens. Background This experiment focused on a simple lens system. A simple lens is a piece of glassware that is spherical on one side and flat on another side‚ or spherical on both sides. There are two different types of lenses
