What is the complementarity principle?
a. If an electron or photon is a particle, it cannot be a wave.
b. If an electron is being observed as a particle, it cannot be simultaneously observed as a wave.
c. A complete description of an electron or photon must include its particle and wave characteristics.
d. If electrons act as particles in an experiment, then the photons in the experiment behave as waves.

A thin beam of light of wavelength 625 nm goes through a thin slit and falls on a screen 3.00 m past the slit
You observe that the first completely dark fringes occur on the screen at distances of ±8.24 mm from the central bright fringe, and that the central bright fringe has an intensity of 2.00 W/m2 at its center. (a) How wide is the slit? (b) What is the intensity of light at a point on the screen that is one-quarter of the way from the central bright fringe to the first dark fringe?
