Consider the following experiment for single slit diffraction: 00 You illuminate the slit with two different lasers, first with a wavelength of 500 nm and then with a wavelength of 700 nm. You observe the distance between the first intensity minima of the two lasers to be 0.4 mm. If the screen distance D = 120 cm, what is the slit width a? Select one: 300 μm 600 μm 100 μm 500 μm
