Unformatted text preview: 600nm which are then absorbed by the retina in the eye. The red solution absorbs light of the highest energy level because it absorbs light that is mostly below 600nm in wavelength, which is also the range of visible light possessing the greatest amount of energy. The spectrum of the green solution looks as expected because it peaks at 520nm, which is the range of transition from blue to yellow light. Green would be expected to be between these two colors because in pigments, green is the mixture of yellow and blue. The unknown sample is orange colored, and transmits most of the light in the 550-700nm range. This is the range that is expected because orange light has a wavelength of approximately 600nm. The unknown sample’s identity is REPLACE WITH IDENTITY OF SAMPLE. The standard curve prepared for the unknown sample is used to identify a solution’s concentration by examining the absorbance and transmittance of the substance....
