Hi, I would need help with this problem.(adsbygoogle = window.adsbygoogle || []).push({});

A beam of light (628 nm) passes through 2 parallel slits in a screen, forming a pattern in which the interfringe is equal to 0,5 cm. If the distance between the slit and the screen is equal to 2,4 m, what is the distance between the slits?

The answer is 0,3 mm but I always get 1,5 which is way too high

I don't really understand how to use the interfringe value...
