in optical instruments,while measuring the lenght,the object and the image must overlap,if not it would show parallax error.

Parallax error is the most common source of both systematic and instantaneous anomaly in experiments involving analogue measurement and great care should be taken to avoid it when recording data, supported also by repetition of each independent variable data collection stage.
When a readng is taken from an analog meter, the pinter must be viewed correctly as it is a short distance away from the scale, so if read from one side, an error of several divisions will occur. To avoid this error the meter should be read from a position directly above the pointer. To help avoid this error most meters have a mirror in the scale so that the error may be dicerned more readily.
Did you ever sit in the passenger seat and look at the fuel gauge on the dash? You see the gauge from the side so it appears that the needle is pointing to Empty. The driver is looking straight at it so the driver sees the actual reading to be a quarter of a tank. That was a parallax error that your observation position created.

A parallax error is when the experimenter reads or record incorrect measurement of a quantity.This may happen because he/she does not know how to read the instrument and can be prevented by learning to read the instrument correctly.
Random errors can be parallax and from changes in the environment.
The parallax error happens when you take a picture using your digital camera and the picture does not appear to look the same as it did in the viewfinder. The cameras that may have this error occur are the twin lens reflex cameras and cameras that include viewfinders.
This is called parallax error.
There is no such way to avoid parallax error, you just have to be careful.. :)
Parallax error should be avoided during titration experiments because it can lead to inaccurate volume readings. Parallax error occurs when the observer's eye is not directly in line with the measurement markings, causing a shift in perceived position. This can result in incorrect volume measurements and affect the precision and accuracy of the titration results.
By looking at the object straight, instead of from either side?
Parallax error refers to the apparent shift in the position of an object when viewed from different angles, causing a discrepancy in measurement. This error occurs when the observer's line of sight is not aligned with the measurement scale, leading to inaccurate readings. It's commonly encountered in various fields, such as photography, surveying, and instrumentation, where precision is crucial. To minimize parallax error, it's important to ensure proper alignment and viewing angles when taking measurements.
:parallax error occurs when the line of sight or measure is not at right angles ( perpendicular ) to the objects being measured. Any distance between the object and the measuring reference ( for example a rule ) will cause a misreading. This error will increase as the distance between the object and the reference increases.
