Explain how spectrometer works by drawing a labelled flow diagram showing the main components of spectrometer and briefly state the purpose of the components
A spectrometer is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum. The main components of a spectrometer include:
1. Light Source: The light source emits light that is directed into the spectrometer for analysis.
2. Entrance Slit: The entrance slit controls the amount and direction of light entering the spectrometer.
3. Collimating Lens: The collimating lens focuses the light from the entrance slit into a parallel beam.
4. Diffraction Grating: The diffraction grating disperses the light into its component wavelengths.
5. Detector: The detector measures the intensity of light at different wavelengths.
6. Output Device: The output device displays or records the results of the analysis.
The purpose of these components is as follows:
- Light Source: Provides the light to be analyzed.
- Entrance Slit: Controls the amount and direction of light entering the spectrometer.
- Collimating Lens: Focuses the light into a parallel beam for analysis.
- Diffraction Grating: Disperses the light into its component wavelengths for analysis.
- Detector: Measures the intensity of light at different wavelengths.
- Output Device: Displays or records the results of the analysis.
