1. How many dark fringes will be produced on either side of the central maximum if light ( = 553 nm) is incident on a single slit that is 5.1 10-6 m wide?
2. sin theta = m (lamba/ W)
lamba = wavelength
W = slit width
m - number of fringes
3. I have no idea how to do this without at least an L or theta.
Does anyone know what I am to do?
