INSTRUMENT- DEFINITION. “ The . device used for comparing the unknown quantity with the unit of measurement or standard quantity is called a Measuring Instrument.”. . The selection of measuring instruments depends on the measurement to be performed.. 1. The . range and magnitude of the parameter to be measured and the accuracy of the. measurement (the instrument should have the range to cover effectively the range. INTERFERENCE:. When two wave trains of the same frequency & the same amplitude traveling in the same direction are superimposed on one another they produce interference. If at any point the waves are in phase, there is an increase in resultant amplitude, i.e. .
