Visual spectrum This site, closely coupled to The Natures of the Stars and The Hertzsprung- Russell HR Diagram , provides an introduction to the spectra of stars and allied celestial objects. Here we examine the principal way in which astronomers have learned so much about the stars. Spectra has been translated into Romanian. The visual spectrum Pass sunlight through a triangular prism or bounce it off the finely grooved surface of a compact audio disk and see it break merrily into a band of pure sparkling color, its “spectrum,” familiar in the colors of a rainbow, in light glittering from newly fallen snow, in the rings and haloes around a partly- clouded Sun and Moon, in the flash of a cut diamond, and in so many other facets of nature. The classic colors red, orange, yellow, green, blue, and violet connect in a seemingly infinite number of shades, one blending smoothly into the next. Together they constitute the “visual spectrum” or “optical spectrum” because it is the part of the full spectrum that is seen with the human eye. The rainbow is a natural spectrum caused by the refraction and reflection of sunlight through raindrops, and shows that sunlight consists of a continuous run – – a continuum — of colors from red to violet. Note the fainter outer bow caused by double reflections inside the raindrops. Kaler Extending the light: Most of the energy of the Universe is transported in this way, by radiation.

I would stick to group 1, 2, 6 and 7 elements and avoid high atomic numbers as the students will be drawing the structures.

References Generic Radiometric Dating The simplest form of isotopic age computation involves substituting three measurements into an equation of four variables, and solving for the fourth. The equation is the one which describes radioactive decay: The variables in the equation are: Pnow – The quantity of the parent isotope that remains now.
This is measured directly. Porig – The quantity of the parent isotope that was originally present. This is computed from the current quantity of parent isotope plus the accumulated quantity of daughter isotope. Standard values are used, based on direct measurements. Solving the equation for “age,” and incorporating the computation of the original quantity of parent isotope, we get: Potential problems for generic dating Some assumptions have been made in the discussion of generic dating, for the sake of keeping the computation simple.
