There are two errors called Parallax — one is parallax and the other is aberration.

When you have two items in a line ( 2 items define a line — can’t miss), they can look out-of line when you (the third item) is not lined up with the first two. Example, when looking at a sensitive galvanometer they put a mirror under the pointer. When you look at the pointer, the voltage read could be off, but when you look at the reflected pointer — setting it up to be right on top (err, on the bottom) of the pointer — then the read voltage is correct. The error of positioning, parallax, is corrected.

Aberration is a similar error but caused by the motion of the items.

Answer 2

parallax error is the shift in apparent position of an object due to different viewing positions .. parallax error is caused by humans , while measuring a quantity if your eyes in not at the proper angle to the scale you are reading , it depends upon the line of sight.
