The critical angle can be calculated by taking the inverse-sine of the ratio of the indices of refraction. The ratio of nr/ni is a value less than 1.0. In fact, for the equation to even give a correct answer, the ratio of nr/ni must be less than 1.0. Since TIR only occurs if th...
The equation is: θcrit = sin-1(nr/ni) We have: θcrit = The critical angle. nr = refraction index. ni = incident index. Critical angle Questions: 1)What must be the angle of incidence for there to be total internal reflection of a ray going from water (nw = 1.3) to glass ( ...

If the functionf(t) is derived from dimensional considerations alone, one speaks of self-similarity of the first kind. An example is\(f(t)\; = \;\sqrt {\lambda t} \)for the diffusion equationZ,t=λΔZ. In more complicated equations, the limit of self-similar solutions can be singul...
(a) A tank containing methanol has walls 2.50 cm thick made of glass of refractive index 1.550. Light from the outside air strikes the glass at a 41.3° angle with the normal to the glass. Find the angle the light makes with the normal in the methanol. (...

The amplitudes of an energy-eigenstate on different layers are related by the Schrodinger equation. A (2s × 2s shaped) transfer matrix Tn generally transforms the amplitudes on the (l − r1)th ~ (l + r2 − 1)th layers to those on the (l − r1 +...
Equation (27) has also been tested for the case of biaxial tension loading, λ=1, of nodular cast irons where a higher fatigue limit is predicted. In contrast to torsion loading where the critical flaw size is several times larger than that in tension, the critical flaw size in biaxial te...
