The wavelength of light of a particular colour is 5800 Å.
Express it in nanometre.
Explain the terms : Least count of a screw gauge.
How are they determined?
What do you mean by zero error of a screw gauge? How is it accounted for?
The pitch of a screw gauge is 1 mm and the circular scale has 100 divisions. In measurement of the diameter of a wire, the main scale reads 2 mm and 45th mark on the circular scale coincides with the base line. Find
(i) The least count and
(ii) The diameter of the wire.
The main scale of vernier callipers has 10 divisions in a centimetre and 10 vernier scale divisions coincide with 9 main scale divisions. Calculate
- pitch
- L.C. of vernier callipers.
What do you understand by the term zero error?
State the formula for calculating the least count of screw.
Consider the following case where the zero of vernier scale and the zero of the main scale are clearly seen. If L.C. of the vernier calipers is 0.01 cm, write the zero error and zero correction of the following.
