Light waves, for which the electric field is given by Ey(x,t)=Emaxsin[(1.40×107m−1)x−ωt], pass through a slit and produce the first dark bands at ±28.6∘ from the center of the diffraction pattern.
Part A
What is the frequency of this light?
Part B
How wide is the slit?
Express your answer with the appropriate units.
Part C
At which positive angle will the next dark band occur?
