How far apart are the two slits

Reference no: EM13663457

Coherent light of frequency 6.2010¹⁴ Hz passes during two thin slits and falls on a screen 80.0 cm away. You observe that the third bright fringe occurs at ±3.51 cm on either side of the central bright fringe.

1. how far apart are the two slits?

2. At what distance from the central bright fringe will the third dark fringe occur?
