Final answer:
A solution's apparent color is due to the complementary color being absorbed. A green solution absorbs red light, an orange solution absorbs blue light, a red solution absorbs green light, and a blue solution absorbs orange light.
Step-by-step explanation:
The color absorbed by a solution that appears a particular color can be understood using the concept of complementary colors. The color we see is the one that is reflected or transmitted, while its complementary color is the one absorbed. Here is the explanation for each given color:
- Green - A solution that appears green absorbs the complementary color, which is red.
- Orange - If a solution appears orange, it absorbs the complementary color, blue.
- Red - A red-appearing solution absorbs green light.
- Blue - A blue solution absorbs orange color.
Furthermore, as per the data provided, a complex that appears green absorbs photons in the red and green wavelengths.
