The function of the collimator in a spectrometer is:
Correct answer: A. To produce a parallel beam of light
- A. To produce a parallel beam of light
- B. To make them mutually perpendicular
- C. To filter the light
- D. No function
Explanation
The collimator in a spectrometer is used to produce a parallel beam of light from the source. This ensures that the light entering the spectrometer is parallel.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
