Question

Reading a measurement from a scale at an angle, rather than from directly in front, can lead to a different value. What source of uncertainty does this describe?

विकल्प

• Parallax

• Poor instrument

• User skill

• Outside factors

Answer 1

Parallax

Reason:

Parallax error happens when you don't look straight at the scale, causing a wrong reading. It’s a method-related uncertainty in measurement.
