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 bright spot on the screen change if the slit width is halved?
- The width of the central bright spot does not depend on the slit width.
- It will decrease to one-quarter its original size.
- It will decrease to one half its original size.
- It will become four times as large.
- It will double.
