Light of a single wavelength is incident normally on a diffraction grating. The resulting diffraction pattern is displayed on a screen. Which change makes the first orders of intensity maxima further apart from each other on the screen?
Aplacing the screen closer to the diffraction grating
Busing a diffraction grating with less separation between adjacent slits
Cusing a diffraction grating with more slits but keeping the same separation between adjacent slits
Dusing light with a shorter wavelength
✓ Correct answer
B: using a diffraction grating with less separation between adjacent slits
