The reason for serial of light spots appearing on the measuring scale is due to an effect known as parallax error. Parallax error occurs when the measurer's eye is not directly over the scale, causing the light spots to appear in a series. This can be caused by the measurer moving their head or body while taking a measurement, or the measurer not being in the correct position to take an accurate measurement. The light spots will appear in a series because the measurer's eye is seeing the measurer's scale from different angles. As the measurer moves, the angles change and the light spots appear in a series. This can lead to inaccurate measurements, as the measurer may not be able to accurately read the scale due to the parallax error. To remedy this, the measurer should make sure they are in the correct position before taking a measurement, and should not move while taking a measurement.
Use a tape measurer.
