Textbook Question

Chapter 2, Problem 1ASA

Do experimental measurements give the true value of a physical quantity? Explain.

Expert Solution & Answer

To determine

Whether true value of a physical quantity is obtained in experimental measurements or not.

Answer to Problem 1ASA

The experimental measurements do not give the true value of a physical quantity. There will be some uncertainty or error inherent to every measurement made.

Explanation of Solution

In every measurement taken by any instrument, there is a finite probability of having an experimental uncertainty or error irrespective of the quality and care taken during measurement. The type and severity of the errors may vary depending on the instrument, the technology of operation, and quality of operation.

Obtaining a true value of any quantity in any measurement is practically not possible. However the measurement can be taken with at most accuracy and precision if proper advanced instruments are used. Repetition of measurement and taking average of all the measurements taken helps to find the most reliable values of the parameters. Every physical parameter demands an order of accuracy and precision depending on the physical environment, and the observer needs to ensure only whether the measurement meet that criteria.
