Screw Gauge

A screw gauge is an instrument made up of a screw widely used for accurate measurements. Various components in engineering and physics require a screw gauge to measure the objects with an accuracy of 0.001 cm. The operation supported by a screw gauge is a component measurement. There are specific variants in a screw gauge […]

Numerical problems on Heisenberg’s uncertainty principle

According to Heisenberg’s uncertainty principle, there is uncertainty while measuring a particle’s variable. The principle, which is commonly applied to a particle’s position and momentum, states that the more specifically a position is known, the more uncertain the momentum is, and the same happens when the momentum is known precisely and the position is uncertain.

Manometer

Introduction  A manometer is scientific equipment that is used to measure the pressures of gases in the atmosphere. Open manometers are used to measure the pressure of a gas in relation to the surrounding atmosphere. A mercury or oil manometer measures gas pressure by measuring the height of a mercury or oil fluid column that

Heisenberg Uncertainty principle Equation

The uncertainty principle, also known as the Heisenberg uncertainty principle or the indeterminacy principle, is a statement made by German physicist Werner Heisenberg in 1927. It states that an object’s position and velocity cannot be measured precisely at the same time, even in theory. In reality, the concepts of precise position and exact velocity have

Ganongs Potometer

It is possible to utilize a potometer, also called a transpirometer, as a tool for measuring the rate of water uptake by a leafy shoot, which is nearly equal to the rate of water loss by transpiration. The processes of photosynthesis and transpiration are responsible for water uptake. Ganongs Potometer: An overview Ganong’s Potometer is

Figure of Merit of a Galvanometer

A galvanometer is an electrical flow estimation instrument that is electromechanical. During the earlier times galvanometers were uncalibrated, yet later forms alluded to, as ammeters were adjusted and will unequivocally distinguish the current stream. A galvanometer answers an electrical flow through a loop during a consistently attractive motion by avoiding a pointer. Galvanometers are frequently

Experiments on using screw gauge (micrometre)

Screw Gauge  A screw gauge is the most accurate device for measuring a spherical or cylindrical object with high precision. Untrained hands may find it difficult to utilise a screw gauge that has been fine-tuned to an extreme degree. Using this post, we hope to raise awareness among anyone and everyone about the fundamentals of

Experiments based on using Vernier callipers and screw gauge

The experiments based on using vernier calliper and screw gauge deal with measuring the linear dimensions of an object. In simple words, it gives the distance between two points in a straight line. Vernier callipers and screw gauge provide accurate dimensional values of the object, with high sensitivity to any change in the dimensions.  These

Errors In Measurement

All experimental study is based on the collection of data. Without ever-increasing standards of accuracy, many of the major scientific discoveries would not have been conceivable. Compared to other measures, ours is the most precise in the industry. Comparing an unknown weight to a known weight is how we measure, much as vegetable dealers do.

Error Analysis for Physical Quantities

Introduction All experimental science and technology is based on measurement. Students must understand the concept of analysing a measurement mistake in the first topic of fundamental physics in high school and college. There is no such thing as a fully exact measurement of a physical quantity. It is therefore critical to understand how much the
