Light of wavelength l is normally incident on a slit of width a = l. An observer at q = 0° and a large distance away measures an intensity of W/m2.
a) Identify the phasors from the figure below that correspond to angles of observation sinq = 0.125, sinq = 0.25, and sinq = 0.375 by entering the appropriate numbers in the boxes.
The phasor for sinq = 0.125 is number
The phasor for sinq = 0.25 is number
The phasor for sinq = 0.375 is number
b) Now compute the intensity that the observer will measure at the same distance at these angles of observation.
Isinq=0.125 = W/m2
Isinq=0.25 = W/m2
Isinq=0.375 = W/m2
