The wavelength of light is 589 nm. what is its wavelength in Å?
Advertisements
उत्तर
Wavelength of light = 589 nm
1 angstrom = 0.1 nm
We have 589 nm
`589/0.1 = 5890` Angstroms
= 5890Å

Draw a neat and labelled diagram of a screw gauge.
Name its main parts and state their functions.
In the vernier callipers, there are 10 divisions on the vernier scale and 1 cm on the main scale is divided into 10 parts. While measuring the length, the zero of the vernier lies just ahead of the 1.8 cm mark and the 4th division of vernier coincides with a main scale division.
(a) Find the length.
(b) If zero error of vernier callipers is -0.02 cm,
What is the correct length ?
