Answer:
The most precise is 0.0034 m ⇒ 1st answer
Explanation:
Lets revise the meaning of precise
Precision is referred as the closeness of two measurements to one
another.
Highest number with significant digit is the most precise
Ex: Highest significant of optical instrument is the Wavelength of visible (red)
light = 0.00006 cm
Hence the most precise device for measuring length is the given optical
instrument
The difference between accuracy and precise
Accuracy is how close a value is to its true value
Precision is how repeatable a measurement is
We have three numbers
0.0034 m, 45.6 m, and 1234 m
The least precise is 1234 m
The most precise is 0.0034 m
