LACTUER 3 THE MOLECULAR FORMULA / ANALYTICAL

... If you are given the % composition of a compound, here are the steps for finding the empirical formula: 1. Assume you have a 100 g sample. This makes the calculation simple because the percentages will be the same as the number of grams. For example, if 40% of the mass of a compound is oxygen then y ...

Relativistic Doppler Effect of Light and Matter Waves

... −ωt + k · r represents the scalar product of a four component vector (iω/c, k) with the space-time four-vector xµ = (ict, x, y, z). This implies that the four component vector (iω/c, k) is also a four-vector. This is a rather long procedure, but once this fact is established, ( ω, k ) transformation ...

The resulting mechanically robust structure is then painted in gray, which makes the entire plate appear homogeneous in the optical imaging experiments. Plane waves in the rectangular plate are excited by loudspeakers at one end. The resulting behavio ...

ElaStic: A universal tool for calculating elastic constants from first

... Abstract Elastic properties play a key role in materials science and technology. The elastic tensors at any order are defined by the Taylor expansion of the elastic energy or stress in terms of the applied strain. In this paper, we present ElaStic, a tool which is able to calculate the full second-o ...
