Double slit fringe spacing
In a second version of the same wave investigation, in an interference setup from a optics bench investigation, light of wavelength \(580\,\text{nm}\) passes through slits separated by \(0.3\,\text{mm}\). The screen is \(1.4\,\text{m}\) away. Calculate the fringe spacing. Use the diagram first, then calculate the requested value. Enter the numerical result and choose the interpretation that matches the wave meaning.
