- I believe the pure water is set for a transmittance of 100% in order to for a tranmission relative to water

2. Explain why red light was chosen for studying these nickel solutions. What would happen if you selected the green light?
-Red light has shorter wavelenths but more frequency and thus is able to pass through nickel solutions.

3. If pure water has a transmittance of 100%, why does it have an absorbance of zero?
- I'm confused with this question that how can water have an absorbance of zero
