SUMMARY
To determine which diffraction grating has 10,000 lines/cm, utilize a red laser and a detection screen. Shine the laser through each grating and observe the diffraction pattern produced. The grating with 10,000 lines/cm will produce a more closely spaced diffraction pattern compared to the one with 500 lines/cm due to its higher line density. Measure the angle of diffraction for both gratings to confirm the line density based on the observed patterns.
