Question

Explain why it is necessary to calibrate the spectroscope, and briefly outline the procedure that you will use to do this. An example of a calibration process is the following: Thermocouples can be used to measure temperature when it is not practical to do so with a thermometer. Thermocouples measure temperature in terms of voltage, rather than directly on a temperature scale and therefore need to be calibrated. Comparing the thermocouple output with the reading from a highly accurate thermometer allows the correlation between voltage and temperature. Based on the calibration curve below, what is the temperature of a substance measured with a thermocouple reading of 0.498 V?

Explanation / Answer

there can be errors when doing practical and errors can occur from the instrument that we are working with. to minimize these errors we can use a calibration curve.

as well as it can determin the unknown sample value (what we are lookin for) with in the calibration limits.

take Y axis as the measuring instrument value take X axis as the varioble. take exactly known values as the variobles.then measure them and draw the plot.
