Question:medium

If $I_0$ is the intensity of the principal maximum in the single slit diffraction pattern, then what will be the intensity when the slit width is doubled?

Show Hint

Physics Tip : Doubling the slit width makes the central maximum twice as narrow and more concentrated, but its peak height (intensity) remains constant.
