A slit 1.00 mm wide is illuminated by light of wavelength 589 nm. We see a diffraction pattern on a screen 3.00 m away. What is the distance between the first two diffraction minima on the same side of the central diffraction maximum? (Answer: 1.77 mm)

Best ResponseYou've already chosen the best response.1Did your teacher derive the formula \(\lambda = \frac{ax}{D}\)?

Best ResponseYou've already chosen the best response.0I don't have a teacher. I'm selfteaching myself right now. But if that's the right formula, then are we solving for D? What are a and x? I know the other one must be the wavelength.
