2. A match will not spontaneously light until it is struck along the rough surface on the bottom of the match pack. Why? Construct a potential energy diagram with two curves, one for a normal match and one for a "strike anywhere" (does not need to be on a rough surface to light it) match. Clearly label each curve.

Wien's displacement law

Students often get confused between Wien's displacement law and Planck's radiation law. Although both are historically related, yet they are conceptually different. Planck's law helps determine the spectrum of a blackbody, while Wien's law determines the relationship between peak wavelength and temperature.
