A student performing a physics experiment for kids to calibrate the instrument used for experiments identify and briefly explain the type of error he is making

The student is making an instrumental error. This occurs when there is a problem with the instrument used for the experiment. It could be due to a malfunctioning instrument, improper calibration, or incorrect measurement technique. For example, if the student uses a ruler with inaccurate markings to measure distances, it would introduce instrumental errors into the experiment. These errors can significantly affect the accuracy and reliability of the experimental results. To minimize instrumental errors, it is essential to ensure the instruments are properly calibrated and functioning correctly before conducting the experiment.
