(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A Fraunhofer diffraction pattern is produced on a screen 218 cm from a single slit. The distance from the center of the central maximum to the first-order maximum is 7620 times the wavelength (lambda). Calculate the slit width. Answer in __m

2. Relevant equations

3. The attempt at a solution

I have no idea how to even start this problem but this is what I tried.

7620 = (1.5 * 2.18)/a where a is the slit width.

This was not correct. I would really appreciate any kind of help on this!
