Light can pass through different materials, including air, water, and glass. When light passes from one material to another material with a different density, its wavelength may change. However, its frequency does not change. Based on that information and the formula for the speed of a light wave, what can you say about the speed of light in materials of different densities? Explain your answer.

What is the approximate vapor pressure when the gas condenses at 70 degrees celsius

How many grams of oxygen gas will react completely with a block of calcium metal that is 3.0 cm by 3.5 cm by 4.2 cm, if the density of calcium is 1.55 g/ml? show all steps of your calculation as well as the final answer.

Moseley made revisions to the periodic table that resolved some of the problems with mendeleev's version. which of thesewas a result of his revisions to the periodic table? the revised periodic table could account for the discovery of new elements. the revised periodic table could account for variations resulting from isotopesscientists could begin to write new information onto each element. scientists could begin to place the table on a single sheet of paper.
