The wavelength of light of a particular colour is 5800 Å.
Express it in metre.
Name the two scales of a vernier callipers and explain how it is used to measure length correct up to 0.01 cm.
Describe in steps, how would you use a vernier callipers to measure the length of a small rod ?
Up to how many decimal places can a common vernier callipers measure the length in cm?
State the formula for calculating length if:
Number of vernier scale division coinciding with the main scale and number of division of main scale on the left-hand side of zero of vernier scale is known.
A micrometre screw gauge has a negative zero error of 7 divisions. While measuring the diameter of a wire the reading on the main scale is 2 divisions and 79th circular scale division coincides with baseline.
If the number of divisions on the main scale is 10 to a centimetre and circular scale has 100 divisions, calculate
- pitch
- observed diameter
- least count
- corrected diameter.
For what range of measurement is micrometre screw gauge used?
State whether the following statement is true or false by writing T/F against it.
The least count of a screw gauge can be lowered by increasing the number of divisions on its thimble.
