656 nm to m
Understand the Problem
The question is asking to convert 656 nanometers (nm) into meters (m), which involves understanding the relationship between these two units of measurement.
Answer
$6.56 \times 10^{-7}$ m
Answer for screen readers
The final answer is $6.56 \times 10^{-7}$ m.
Steps to Solve
- Identify the conversion factor
To convert nanometers to meters, we need to know that $1 \text{ nm} = 1 \times 10^{-9} \text{ m}$.
- Set up the conversion
Now that we have the conversion factor, we can set it up to convert 656 nm to meters. We use the equation:
$$ \text{value in meters} = \text{value in nanometers} \times \text{conversion factor} $$
- Perform the calculation
Substituting the known values into the equation gives us:
$$ \text{value in meters} = 656 \text{ nm} \times 1 \times 10^{-9} \text{ m/nm} $$
- Calculate the result
Now, we perform the multiplication:
$$ \text{value in meters} = 656 \times 10^{-9} \text{ m} = 6.56 \times 10^{-7} \text{ m} $$
The final answer is $6.56 \times 10^{-7}$ m.
