Question

One-millionth of a meter is
A. Millimeter
B. micrometer
C. nanometer
D. centimeter

Answer 1

One-millionth of a meter sort of commonly actually is the scale used to usually sincerely explicit the diameter of wool fiber, which literally is pretty large in a basically big manner in a diffused way. The micron or micrometer literally is a unit of measure for the center in optical fiber, for which the maximum for all intents and purposes commonplace diameter actually is $62.5$ micrometer, for all intents and purposes opposite to popular belief.

Complete answer:
A micrometer is also referred to as a micron, or so that they for the most part notion. It essentially is an SI derived unit of length, showing how a micrometer for the maximum part is also referred to as a micron, which normally is reasonably vast. The micrometer normally is a commonly commonplace unit of dimension for wavelengths of very infrared radiation in addition to sizes of quite biological cells and bacteria, and grading, wool employing the diameter of the fibers. The width of a fairly unmarried genuinely human hair ranges from approximately $20200\mu m$to, demonstrating how it is an SI derived unit of duration, showing how a micrometer type of is likewise known as a micron, normally contrary to famous belief. The longest surely human chromosome essentially is about $10\mu m$in period, which surely indicates that it is an SI derived unit of length, showing how a micrometer essentially is likewise known as a micron, which in reality is quite enormous. Around $100\mu m$ ($0.1$ millimeters) essentially is the smallest component visible to the naked eye, pretty similarly showing the way it for the most part is an SI derived unit of the period, displaying how a micrometer for all intents and functions is likewise referred to as a micron in a subtle manner.

Hence, the correct answer is option (B).

Note: A micron is described as a fairly little pretty awful lot a couple of twenty-five thousandths of an inch, kind of contrary to the famous notion. ISM offers fluid, fuel, and airflow management components several of which especially comprises clear out mesh as a thing apart, which mainly within reason are large.
