Understand that visible light is characterized by its wavelength, which determines its color.
Recall the approximate wavelength ranges for visible colors: Violet (~380-450 nm), Blue (~450-495 nm), Green (~495-570 nm), Yellow (~570-590 nm), Orange (~590-620 nm), and Red (~620-750 nm).
Compare the given wavelength of 700 nm to these ranges to identify the corresponding color.
Since 700 nm falls within the range of about 620-750 nm, it corresponds to the color red.
Therefore, light with a wavelength of 700 nm is red in color.
