Three slits, each seperated from its neighbor by 0.06 nm, are illuminated by a coherent light source of wavelength 559 nm. the slits are extremely narrow. a screen is located 2.5m from the slits. the intensity on the centerline is 0.05w/m^2. consider a location 1.72 cm from the centerline. (a) draw the phasors, according to the phasor model for the addition od harmonic waves, appropriate for this location.
(b) from the phasor diagram, calculate the intensity of light of this location.
