Question:
Match the instruments with the parameters they measure:
List-1 Instrument List-2 (Parameter) A Autocollimeter \( \text{Angular error} \) B Hygrometer \( \text{Humidity} \) C Nephelometer \( \text{Density} \) D Mass spectrometer \( \text{Molecular weight} \)
Match the instruments with the parameters they measure:
| List-1 | Instrument | List-2 (Parameter) |
|---|---|---|
| A | Autocollimeter | \( \text{Angular error} \) |
| B | Hygrometer | \( \text{Humidity} \) |
| C | Nephelometer | \( \text{Density} \) |
| D | Mass spectrometer | \( \text{Molecular weight} \) |
Show Hint
Autocollimeter → Angular error; Hygrometer → Humidity; Nephelometer → Density; Mass spectrometer → Molecular weight.

The Correct Option is A
Solution and Explanation
- Autocollimeters are used to measure angular displacement → Angular error (Q)
- Hygrometers measure the moisture content in the atmosphere → Humidity (S)
- Nephelometers assess the turbidity or particle density in fluids → Density (T)
- Mass spectrometers determine the masses of particles → Molecular weight (R)
- Hygrometers measure the moisture content in the atmosphere → Humidity (S)
- Nephelometers assess the turbidity or particle density in fluids → Density (T)
- Mass spectrometers determine the masses of particles → Molecular weight (R)
