Light of wavelength 490 nm is incident on a narrow slit. The diffraction pattern is viewed on a screen 3.6 m from the slit. The distance on the screen between the central maximum and the third minimum is 2 cm. What is the width of the slit?

2. Relevant equations

3. The attempt at a solution

Not sure where I need to start. Can someone help me out
