required practical 2 - eye piece graticule and stage micrometer

Question 1

step 1 (for calibrating eyepiece micrometer)

Answer 1

> align eyepiece graticule (arbitrary scale) with the stage micrometer (known scale)

Question 2

step 2

Answer 2

> count how many divisions on the eyepiece micrometer correspond to a set number of stage micrometer divisions
(e.g - for every 10 stage micrometer divisions there are 21 eyepiece graticule divisions)

Question 3

step 3

Answer 3

> calculate how big one eyepiece division is
- must know how long every division on stage micrometer is

Question 4

step 4

Answer 4

work out division
