The wavelength of light of a particular colour is 5800 Å.
Express it in nanometre.
Name the two scales of a vernier callipers and explain how it is used to measure length correct up to 0.01 cm.
State one use of a screw gauge.
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.
How can the least count of a screw gauge be decreased?
State the formula for calculating length if:
The reading of the main scale is known and the number of vernier scale divisions coinciding with the main scale is known.
State the correction if the negative error is 7 divisions when the least count is 0.01 cm.
Find the volume of a book of length 25 cm, breadth 18 cm and height 2 cm in m3.
State whether true or false. If false, correct the statement.
With the help of vernier caliper we can have an accuracy of 0.1 mm and with screw gauge we can have an accuracy of 0.01 mm.
