Vernier scale. The figure below shows a scale found on instruments such as a micrometer caliper used for accurately measuring dimensions of objects. The lower scale slides along the upper scale and is used to interpolate between the markings on the upper scale. In

(a) The reading (at the left-hand 0 of the lower scale) is between 1.4 and 1.5 on the upper scale. To find the exact reading, observe which mark on the lower scale is aligned with a mark on the upper scale. Because the 6 on the lower scale is aligned with the upper scale, the correct reading is 1.46. Write the correct readings in

(b) and (c) and indicate how many significant figures are in each reading.

The reading is 1.46.

Here the left hand 0 of the lower scale is in between 1.1 and 1.2. Now the 8 on lower scale is aligned with a mark on the upper scale. Hence the correct reading is 1.18.

Here the 0 of the lower scale is in between 0.7 and 0.8. Now the 1 on lower scale is aligned with a mark on the upper scale. Hence correct reading is 0.71.

The reading is 1.46.
