hey ! hi
iam gonna tell you how to find the least count of a vernier scale.
first of all lc is the least possible measurement made by an apparatus this stand as a symbol of its accuracy
now coincide the 0 of main scale to that of vernier scale
if n main scale divisions = m verneier scale divisons
then 1 vsd = n/m msd
then lc = 1msd - 1 vsd (if n>m)
= 1 vsd - 1 msd (if n<m)
i think 0.01
Least count refers to the highest level of accuracy that can be achieved in measurement. The general formula is: LC = (Value of 1 Main Scale Division) / (Total number of Vernier scale divisions).
The formula for calculating the least count of a vernier height gauge is: Main scale division / (Total number of divisions on the vernier scale - 1). This formula helps determine the smallest measurement that can be read from the gauge.
The least value which can be measured from any measuring instrument or device is called its least count. Generally the least count of a vernier caliper is 0.02mm.You can get a least count of 0.01mm in Digital vernier caliper.
The formula to calculate the measurement using a vernier scale is: Measurement = Main scale reading + (Vernier scale reading × Least count) The least count is determined by the difference between one main scale division and one vernier scale division. This allows for more precise measurements by accounting for the additional fractional value indicated by the vernier scale.
The least count of a vernier scale in a diffraction grating is typically determined by the formula for the number of lines per unit length on the grating. By dividing the distance between two adjacent lines on the scale by this number, you can calculate the least count of the vernier scale.
Least Count [L.C]:-Least count is minimuim acuurate value meauserd by instrument.Least Count of Vernier Callipers:-The minimum value measured is 0.1mm but nowa days [l.c] is of 0.5mm.'
The least count of a vernier depth micrometer can be calculated using the formula: [ \text{Least Count} = \text{Value of one main scale division} - \text{Value of one vernier scale division} ] Typically, for a depth micrometer, the value of one main scale division is 1 mm, and if the vernier scale has 10 divisions that equal 9 mm, the least count would be: [ \text{Least Count} = 1 , \text{mm} - \left(\frac{9 , \text{mm}}{10}\right) = 0.1 , \text{mm} , \text{or} , 0.01 , \text{cm}. ]
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.
