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 n lambda. This function multiplies index of refraction on both sides of Snell’s 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■
ANSWER: sine [or sin; accept sine theta or sine lambda]
