Question

figure 16.1 shows a vernier scale and micrometer scale what is the rading on the vernier scale

Answer 1

Answer:

The main scale reading is the first reading on the main scale immediately to the left of the zero of the vernier scale (3 mm), while the vernier scale reading is the mark on the vernier scale which exactly coincides with a mark on the main scale (0.7 mm). The reading is therefore 3.7 mm.
