The correct Answer is:
To solve the question "1 m = ___ nm", we need to convert meters to nanometers. ### Step-by-Step Solution: 1. **Understand the Units**: - 1 meter (m) is a basic SI unit for measuring distance. - 1 nanometer (nm) is a much smaller unit of length. 2. **Know the Conversion Factor**: - We need to know how many nanometers are in one meter. - The conversion factor is: \[ 1 \text{ m} = 10^9 \text{ nm} \] - This means that 1 meter is equal to 1 billion nanometers. 3. **Perform the Conversion**: - Since we are asked to find out how many nanometers are in 1 meter, we can directly use the conversion factor: \[ 1 \text{ m} = 10^9 \text{ nm} \] 4. **Write the Final Answer**: - Therefore, the answer to the question is: \[ 1 \text{ m} = 10^9 \text{ nm} \] ### Final Answer: 1 m = 10^9 nm ---
