1 fermi is equal to

Options

A. `10^(-15)` m
B. `10^(15)` m
C. `10^(-12)` m
D. `10^(12)` m

Answer

To determine the value of 1 Fermi in meters, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Unit**: Recognize that Fermi is a unit of length. It is primarily used in the field of nuclear physics to measure very small lengths, such as the diameters of atomic nuclei.

2. **Understand the Scale**: Since the nuclear diameter is extremely small, we need a unit that can accurately represent these minuscule measurements. This is where the Fermi comes into play.

3. **Conversion to Meters**: The relationship between Fermi and meters is defined as follows:
\[ 1 \text{ Fermi} = 10^{-15} \text{ meters} \]

4. **Conclusion**: Therefore, we conclude that:
\[ 1 \text{ Fermi} = 10^{-15} \text{ m} \]

### Final Answer:
1 Fermi is equal to \( 10^{-15} \) meters.
