Print your name and NetID legibly. Follow the guidelines and format given in the syllabus. Staple multiple
pages. Put all units. 1. Solids are made of nuclei and electrons. Much of our information about solids is found by studying
them using other particles like light (photons) and neutrons. According to the laws of quantum
mechanics, all particles act like waves and waves act like particles, with the relation
h / p , where
