The wavelength of light of a particular colour is 5800 Å.
Express it in nanometre.
The size of bacteria is 1 µ. Find the number of bacteria present in 1 m length.
Name the part of the vernier callipers which is used to measure the following
Thickness of a pencil.
State one use of a screw gauge.
What is the need for measuring length with vernier callipers?
Define the term pitch.
State the correction if the negative error is 7 divisions when the least count is 0.01 cm.
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.
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.
