Please explain this problem md how to solve.

A single-slit diffraction pattern is formed on a distant screen. Assuming the angles involved are small, by what factor will the width of the central bri spot on the screen change if the slit width is tripled? O It will become three times as wide. O It will decrease to 1/9 of the original width. O The slit width does not affect the width of the central bright spot. It will decrease to 1/3 of the original width. O It will become nine times as wide
