EXPERIMEN T 2 Experimental Uncertainty (Error) and Data Analysis T Advance Study Assignment Read the experiment and answer the following questions. I. Do experimental measurements give the true value of a physical quantity? Explain. 2. Distinguish between random (statistical) error and systematic error. Give an example of each. 3. What is the difference between measurement accuracy and precision? Explain the general dependence of these properties on the various types of errors.

What is systematic uncertainty? A source of measurement uncertainty caused by repeatable imperfections in the experiment. A source of measurement uncertainty caused by unknown and unpredictable changes in the measuring instruments or environmental conditions. The approximated spread in a measured set of data. The difference between a measured value and a predicted value.

The final step of experiment in Lab6 is to estimate the systematic uncertainty of your final measurement due to the variations of the parameters you measured in the lab. Equations (6.7) and (6, 8) in your lab manual give expressions for e/m and the relative error of e/m due to all of the parameters measured in the lab. (Sigma _e/m/e/m)^2 = (sigma _v/V)^2+(2 sigma _O/I^2+2 sigma _R/R)^2+(2 sigma _r/r))^2 Term # 1 2 3 4 Assume your mean measurements of...

Use uncertainty analysis to estimate what is the smallest wavelength separation that can be resolved. In other words, what uncertainty would be expected for measurements of wavelength with the spec- troscope? Assume that the diffraction grating has 600 lines/mm and you are looking at wavelengths around 600nm. Use the error estimates outlined in the error analysis section. Will you be able to reliably resolve all the spectral lines of helium, sodium, and cad- mium? If not, list what sources of...

1. When measuring the inner and outer diameters of the hollow block, what were the main sources of experimental error? Group these errors into those that are systematic and those that are random. 2. How could you improve the measurement of the block diameters? In particular, consider how to improve the accuracy of the average value of diameter and how to reduce the uncertainty in the measurement. 3. To how many significant figures can you state the volume of material...
