Least count of vernier scale in spectrometer
Nettet18. nov. 2024 · The spectrometer has around its base a scale graduated in degrees, with a least count of half a degree. There is also a vernier scale above the main one, which runs from 0 to 30, subdivided into smaller units; this vernier scale measures arcminutes. Nettet1.Determine the least count of the spectrometer. 2.Place the prism on the prism table with its refracting angle A towards the collimator ... 4.Note corresponding main scale and vernier scale reading in both vernier (vernier I and vernier II). 5.Carefully remove the prism from the prism table.

Nettet21. feb. 2024 · Fig. 1 Spectrometer concept, experimental setup, and static measurement. ( A) Counterpropagating soliton frequency combs (red and blue) feature repetition rates that differ by Δ fr, phase-locking at the comb line with index μ = 0 and effective locking at μ = N, thereby setting up the vernier spectrometer. Tunable laser and chemical ... NettetCalculate the least count of this vernier scale. Solution: Given: One main scale division, MSD = 1 mm. 20 vernier scale divisions, VSD = 16 main scale divisions, MSD. Therefore, 1 VSD = 16/20 MSD = 0.8 mm. The least count, LC = 1 MSD – 1 VSD = 1 – 0.8 = 0.2 mm. How to Read Vernier Calliper?
NettetThe least count can be calculated by dividing 1 cm by the number of divisions that lie between a unit. This way a main scale which contains 10 divisions in a centimeter will have a least count of 1/10 = 0.1cm or 1 mm. Similarly the vernier scale is also normally divided into ten equal parts. Count the divisions on the vernier scale just to make ...
