The wavelength of light of a particular colour is 5800 Å.
Express it in metre.
Draw a neat and labelled diagram of a vernier callipers. Name its main parts and state their functions.
A screw gauge has a least count 0.001 cm and zero error +0.007 cm. Draw a neat diagram to represent it.
Why is the metre length in terms of the wavelength of light considered more accurate?
(a) A vernier scale has 20 divisions. It slides over the main scale, whose pitch is 0.5 mm. If the number of divisions on the left hand of the zero of vernier on the main scale is 38 and the 18th vernier scale division coincides with the main scale, calculate the diameter of the sphere, held in the jaws of vernier callipers.
(b) If the vernier has a negative error of 0.04 cm, calculate the corrected radius of the sphere.
The Wavelength of a particular colour is 5400Å. Express it in nanometer and metre.
