To convert the length from nanometers (nm) to Angstroms (Å), we need to know the conversion factor between these two units. 1 nanometer equals 10 Angstroms because an Angstrom is 10^-10 meters and a nanometer is 10^-9 meters, making an Angstrom one-tenth the size of a nanometer.
Given that the length is 400 nm, we calculate the equivalent in Angstroms by multiplying 400 by 10:
400 nm * 10 = 4000 Å
Therefore, none of the options A (3000 Å), B (300 Å), C (30 Å), or D (3 Å) are correct. The length of 400 nm equals 4000 Å.
