The vernier constant of a spectrometer is the smallest division on the scale that can be read. It is used to determine the angular separation between spectral lines.
The difference between one main scale division and one vernier division is called vernier constant. this is the minimum length which can be measured accurately with the help of a vernier calipers. it is also called the least count of a vernier. Value of one main scale division is "1 mm" and value of one vernier scale division is "0.9 mm".So,the value of vernier constant is "1-0.9=0.1 mm".
No unit for vernier scale coincidence. But as we multiply it by least count which has unit then we get vernier scale reading with the same unit. Of course main scale reading and vernier scale reading would have the same unit
The least count of a vernier scale is calculated by dividing the smallest division on the main scale by the total number of divisions on the vernier scale. This calculation gives the value of one vernier division.
It is the measuring instrument it is invented by verniers its error is very small
A spectrometer is a scientific instrument used to measure properties of light over a specific portion of the electromagnetic spectrum. The least count of a spectrometer is the smallest change in wavelength or frequency detectable by the instrument. To take measurements with a spectrometer, you would typically calibrate the instrument using known standards and then analyze the light source you are interested in by measuring its intensity at different wavelengths or frequencies.
A spectrometer typically has two verniers to enhance measurement precision and accuracy when determining the wavelengths of light. One vernier is used for coarse adjustments, allowing the user to quickly approximate the wavelength, while the second vernier provides fine adjustments for more exact readings. This dual-vernier system helps minimize errors and facilitates more reliable spectral analysis.
The difference between one main scale division and one vernier division is called vernier constant. this is the minimum length which can be measured accurately with the help of a vernier calipers. it is also called the least count of a vernier. Value of one main scale division is "1 mm" and value of one vernier scale division is "0.9 mm".So,the value of vernier constant is "1-0.9=0.1 mm".
the instrument can be made more sensitive by making vernier constant less ie by incresing the no of division on vernier scale or by decreasing the value of main scale.
It is to minimize the error percentage of parallax. Also we can easily identify if the spectrometer has been moved beyond 270 degrees If we take readings on two scales and then average of it, the value would be more accurate
The value of each main scale divisions is half a degree(30') . The number of vernier scale divisions is 30. 29 main scale divisions are divided into 30 vernier scale divisions (30 VSD = 29 MSD ) Therefore value of 1 VSD = 29/30 MSD. Least Count (L.C.) = 1MSD - 1VSD = 1MSD - 29/30 MSD = 1/30 MSD = 1/30 x 30' (L.C.) = 1' (1 minute)

I guess it is found by vernier as it works on vernier theory -Manasa
Because they were invented by Pierre Vernier in 1631.

where on the vernier caliper would you read to obtain the vernier scale reading
