In a diffraction grating, if the number of slits is increased, what happens to the angular width of the principal maxima?

In a diffraction grating, if the number of slits is increased, what happens to the angular width of the principal maxima?

Step 1: Understand what a diffraction grating is. It is a tool with many slits that spreads light into different directions.
Step 2: Know that when light passes through these slits, it creates patterns of bright and dark areas called maxima and minima.
Step 3: Realize that the principal maxima are the brightest spots in these patterns.
Step 4: Learn that increasing the number of slits means more paths for the light to travel through.
Step 5: Understand that more slits lead to sharper and more defined maxima because the light waves interfere more constructively.
Step 6: Recognize that sharper maxima means they take up less space, which decreases their angular width.
