MCQ
$1\text{ micron}=\frac{1}{1000000}\text{m}$ which of the following is its standard form?
  • A
    $1.1 \times 10^{-5}$
  • B
    $1.6 \times 10^{-5}$
  • C
    $0.1 \times 10^{-6}$
  • ✓
    $1.0 \times 10^{-6}$
✓

Answer

Correct option: D.
$1.0 \times 10^{-6}$
D.  $1.0 \times 10^{-6}$
Solution:
In the scientific notation, a "micro" is always represented by the number $10$ raised to the power of $-6.$ Thus, in the scientific notation, a micron will be represented in a similar manner.
Therefore, a micron will be:
$1\text{ micron}=\frac{1}{1000000}\text{m}$
$=\frac{1}{106}\text{m}\begin{Bmatrix}\text{a}^{-\text{m}}=\frac{1}{\text{a}^{\text{m}}}\end{Bmatrix}$
$1$ micron $= 10^{-6}m$ [Staudand from]
Or, $1.0 \times 10^{-6}$
