Answer:
700 nanometers
Step-by-step explanation:
8 wavelengths had a combined length of 5,600 nanometers.
We want to find the wavelength (in nm) of 1 of those wavelengths.
We will assume all of them are same wavelength. So, we can basically divide the total of 8 wavelengths by 8 to get 1 wavelength. Thus:
5600/8 = 700
Hence,
1 wavelength distance is 700 nanometers (or 700 nm)
