parallax error

Vision error

Answer 1

Answer:

error due to eye vision is termed as parallax error.

Answer 2

Error due to eye vision is termed as Parallax error.

Explanation:

• Change in apparent position of an object due to different viewing points is called parallax.
• Parallax error depends on the angle from which an observer is viewing a scale of measurement.
• This type of error affects telescopes, microscopes, reflex cameras etc.
• One common example of parallax error is while driving a car, person on driving seat views the speedometer correctly but the person on the side will view it differently. This is because there is a certain angle of viewing that the person next to driver seat observes the measurement.
• To avoid parallax error, one must be careful enough to place the object very close to measuring scale and eyes must be directly above the scale so as to cause minimum angle of view.
