The tiny distance between slits can be difficult to measure. But you can use the interference pattern
The tiny distance between slits can be difficult to measure. But you can use the interference pattern to find the spacing. Suppose you illuminate the slits with 589-nm yellow sodium light and observe a 4.50-cm bright-fringe spacing on a screen 1.75 m away. (a) What is the slit spacing? (b) What is the angle for the first-order maximum? [3M+3M]
