- 1Red light is completely absorbed, so no ray emerges.
- 2A full multi-colored spectrum appears.
- 3Only a single red ray emerges; no spectrum forms because monochromatic light has only one wavelength.✓
- 4Multiple red rays emerge at different angles.
Correct answer
Only a single red ray emerges; no spectrum forms because monochromatic light has only one wavelength.
