Round 8: Tossup 7

A constant times this function of n pi x over L gives wave functions that solve the 1D particle in a box. This function is set equal to 1.22 lambda over D then approximated to derive the Rayleigh criterion. This function appears in solutions to the heat equation for rods where the boundary temperatures are fixed at 0. The Davisson-Germer experiment is explained by a law modeling (*) X-ray diffraction in which 2d times this function equals (10[1])n lambda. This function multiplies (10[1])index of refraction on both sides of Snell’s (10[1])law. This function is used to find the component of gravity parallel to an inclined plane. For 10 points, what function equals opposite over hypotenuse? ■END■
