please give me the answer of sources of error in person perception
Personal errors natural errors instrumental errors
Calibration error (the equipment gives the incorrect result) and false assumptions (the sample is uniform and solid).
Not enough information
The reaction may have not been complete yet, therefore resulting in a higher percent yield than 100%
Photoelectric colorimeter is a medical term. Essentially, it is referring to a colorimeter using a photoelectric cell and appropriate filters instead of the eye.
Some common sources of error in filtration include improper filter selection, variations in pressure or vacuum levels, filter clogging, nonuniform particle distribution, and filter damage or leakage. These errors can compromise the efficiency and accuracy of the filtration process.
To use a colorimeter, start by calibrating the device according to the manufacturer's instructions. Then, insert the sample into the colorimeter and follow the prompts to measure the color of the sample. The colorimeter will display the results usually as numerical values or a color reading depending on the device.
By colour base
It is not something that was discovered, it was invented. One of the most popular designs is the Duboscq colorimeter which was invented by Jules Duboscq in 1870.
Typically a colorimeter has three filters. However, this can change depending on the company and type of colorimeter. For example our Gamma Scientific tri-stimulus colorimeter uses four extremely stable colored glass filters in conjunction with high quality silicon photodiodes for increased accuracy. This is done to more accurately match the CIE standard observer functions. These resources may be helpful if you have further colorimeter questions:
Identifying sources of error is important because they can impact the accuracy and reliability of data or results. By understanding these sources, researchers can take steps to minimize their influence and ensure the validity of their findings. Ignoring sources of error can lead to misleading conclusions and flawed interpretations.
Compound error refers to the accumulation of errors in a system or process over time. It occurs when small errors in individual components or stages of a process combine to produce a larger overall error. Sources of compound error can include inaccuracies in measurements, rounding errors, human error, and limitations in equipment or technology.
there are a couple
we are using blank because if we are not inserting anything in colorimeter and keeping it open then the light from the surrounding may affect it's absorbance causing damage
A colorimeter reading is a measurement of the absorbance or transmittance of light by a substance at a specific wavelength in order to determine its concentration or properties. Colorimeters are commonly used in chemistry, biochemistry, and environmental science to quantitatively analyze samples based on their color intensity.
A colorimeter could be used in a breathalyzer test to measure the intensity of color change that occurs when an alcohol-based sample is processed. The color change corresponds to the concentration of alcohol in the sample, allowing for quantitative analysis of blood alcohol content. This measurement can then be used to determine if a person is under the influence of alcohol.
