The wavelength of light of a particular colour is 5800 Å.
Express it in metre.
Which of the following measures a small length to high accuracy : metre rule , vernier callipers or screw gauge?
The least count of a vernier callipers is 0.0025 cm and it has an error of + 0.0125 cm. While measuring the length of a cylinder, the reading on the main scale is 7.55 cm, and the 12th vernier scale division coincides with the main scale. Calculate the corrected length.
A micrometre screw gauge has a negative zero error of 8 divisions. While measuring the diameter of a wire the reading on the main scale is 3 divisions and the 24th circular scale division coincides with baseline.
If the number of divisions on the main scale are 20 to a centimetre and circular scale has 50 divisions, calculate
- pitch
- observed diameter.
- least count
- corrected diameter.
What do you understand by the following term as applied to micrometre screw gauge?
Sleeve cylinder
The Wavelength of a particular colour is 5400Å. Express it in nanometer and metre.
What is the least count in the case of the following instrument?
Spring balance
