Which measurement can be made using a micrometer screw gauge? The turning effect of a spanner
The wavelength of microwaves
The diameter of a wire
The air pressure of a tyre

The measurement that should be used via using the micrometer screw gauge is option  C. The diameter of a wire

It is the device that should be used for measuring the small dimension that should not be measured in an accurate way via the use of an vernier caliper. Also, it contains the high accuracy degree. So the measurement should not be done by turning effect, microwaves wavelength, tyre air pressure

Therefore, the option c is correct.

C. The diameter of a wire

Explanation:

A micrometer screw gauge is a device used for the measurement of small dimensions which may not be measured accurately by the use of a vernier caliper, e.g diameter of a thin wire. it has a high degree of accuracy.

From the given option in the question, the measurement that can be made using a micrometer screw gauge is the diameter of a wire
