Based on the research in Study 1, as the wavelength of light increases, the reflectance of Cyanide: C. increases, then decreases.
Wavelength is simply defined as the distance (in meters) between two (2) successive crests or troughs of a wave. Thus, wavelength refers to the horizontal distance between two adjacent crests or troughs of a wave.
Generally, there is a linear relationship between the wavelength of light and reflectance. Thus, as the wavelength of light increases, the reflectance of Cyanide in Study 1 increases, before it then decreases.
