    Formative Questions   

    1. Which wavelengths of light fall within the range of the visible spectrum?
    2. How does red light compare with blue light in terms of wavelength and energy?
    3. What is the relationship between absorbance and percent transmittance?

    Summative Questions   

    1. How can an absorbance spectrum be used to determine the presence or absence of an unknown molecule?
    2. Would a greater concentration of the same molecule change the absorbance spectrum? Why or why not? Explain.
    3. Examine your experimental findings. Does the absorbance of red dye fall within the range of wavelengths for red light on the visible spectrum? Why or why not? Explain.
    4. If a plant appears primarily green in color, which wavelength(s) of light are most likely absorbed by this plant?
