Light waves, for which the electric field is given by Ey(x,t) =Emaxin|(2x107m-1)x-wt], pass through a slit and produce the first dark bands at ‡30• from the center of the diffraction pattern. What is the frequency of this light? How wide is the slit? At which positive angle will the next dark band occur?

This question is regarding the experiment ’Diffraction and Interference of Light’. a) In a diffraction experiment for a given slit and a given slit-screen distance,would the distance between the dark fringes increase or decrease when a blue laser is replaced with a red laser? Use equations to argue why, in no more than two sentences (Hint: wavelength λblue = 470nm, λred = 700 b) Draw the pattern you observe for two slit interference. Mark clearly the diffraction and the interference parts of this pattern. c) How will the pattern change? When I change the distance between the slits?
