Suppose you are measuring double‑slit interference patterns using an optics kit that contains the following options that you can mix and match: a red laser or a green laser; a slit width of 0.04 0.04 or 0.08 mm; 0.08 mm; a slit separation of 0.25 0.25 or 0.50 mm . 0.50 mm. Estimate the minimum distance L L you can place a screen from the double slit that will give you an interference pattern on the screen that you can accurately measure using an ordinary 30 cm ( 12 in ) 30 cm(12 in) ruler.
