The least count of a spherometer is determined by the thickness of the central disk or screw on the instrument. It is typically calculated as the pitch of the screw divided by the number of divisions on the circular scale. For example, if the screw has a pitch of 0.5 mm and the circular scale is divided into 100 divisions, the least count would be 0.005 mm.

How can you determine the least count of spherometer?
To determine the least count of a spherometer, you measure the total number of divisions on the circular scale and divide it by the total travel range of the micrometer screw. The least count is the smallest incremental distance that can be measured accurately by the spherometer.
What is least count of spherometer?
The least count of a spherometer is typically equal to the smallest increment that can be measured by the device, which is often around 0.01 mm.
How are the pitch and least count of spherometer related?
The pitch of a spherometer is the distance between its tips when its central leg is displaced by one turn of the screw. The least count of a spherometer is the smallest distance it can measure, which is determined by the pitch of the screw. The least count is equal to the pitch of the spherometer divided by the number of divisions on the circular scale.
What shall be the effect on the least count of spherometer if number of division on its circular scale be doubled?
Doubling the number of divisions on the circular scale of a spherometer will decrease the least count by half. The least count is inversely proportional to the number of divisions, so as the number of divisions increases, the least count decreases.
How do you determine the least count of a metric rule?
The least count of a metric rule is determined by the smallest division on the scale of the ruler. To calculate the least count, divide the smallest marked division on the ruler by the total number of subdivisions between two main unit markings. For example, if a ruler has millimeter divisions with half-millimeter markings between each millimeter, the least count would be 0.5 mm.

Why spherometer has 3 legs?
because to determine the radius of curvatureof a given spherica surface by spherometer
Why spherometer is called spherometer?
The reason a spherometer is called a spherometer is because it measures the radius of a sphere.
Why spherometer is so called?
The reason a spherometer is called a spherometer is because it measures the radius of a sphere.
What is spherometer uses?
A spherometer is used to measure the radius of curvature of a curved surface, such as a lens or mirror. It typically consists of three adjustable legs that can be used to determine the radius of the curved surface by measuring the height variation across the surface.
What is the unit of measurement in spherometer?
A spherometer is an instrument for the precise measurement of the radius of a sphere. The spherometer directly measures a sagittal. Since the spherometer is essentially a type of micrometer, it measures very small things like millimeters.
Who invented spherometer?
The spherometer was invented by William Gascoigne in the 17th century. It is a precision instrument used to measure the curvature of spherical surfaces.
What is pitch of spherometer?
The distance moved my the screw in one complete rotation in the circular scale is called the pith of spherometer.
