Question
"Monochromatic light should be used to produce pure spectrum". Comment on this statement.
✓

Answer

No, monochromatic light cannot be used to produce a pure spectrum. A spectrum is produced when a light of different wavelengths is deviated through different angles and gets separated. Monochromatic light, on the other hand, has a single wavelength.
