Lab 6: Inteference and Diffraction: Question 1

The lefthand picture show a "zero measurement" with the same kind of metric screw micrometer you will use in this Lab. Its operation is identical to the operation of the metric screw micrometer described in the Lab manual. The "zero measurement" records the reading of the micrometer after the gap between the (already cleaned) anvil and spindle has been closed. The righthand picture shows the same micrometer being used to measure the diameter of a hair.

What is the zero measurement of the micrometer?   ______ units______

What is the measurement for the hair?   _________ units_____

What is the diameter of the hair?  _______ units______

Estimate the absolute uncertainty in the measurement of the hair.  ______ units_____
