The colour of `I_(2)` is violet because it

Options

A. Absorbs violet light
B. Does not absorb light
C. Absorbs yellow and green light
D. None of the above

Answer

To explain why the color of \( I_2 \) (iodine) is violet, we can break down the reasoning into a few clear steps:

### Step-by-Step Solution:

1. **Understanding Color Perception**:
- The color we perceive is determined by the wavelengths of light that are not absorbed by a substance. When a substance absorbs certain wavelengths, we see the complementary color of those absorbed wavelengths.

2. **Identifying the Color of \( I_2 \)**:
- The color of iodine (\( I_2 \)) is described as violet. This means that the wavelengths corresponding to violet light are what we observe.

3. **Complementary Colors**:
- Each color has a complementary color that is perceived when its corresponding wavelengths are absorbed. For example, the complementary color of violet is yellow.

4. **Absorption of Light by \( I_2 \)**:
- In the case of iodine, it absorbs certain wavelengths of light, specifically those that correspond to yellow and green.

5. **Conclusion**:
- Since iodine absorbs yellow and green light, the color that we see is the complementary color, which is violet (or more accurately, a purpley violet).

### Final Answer:
The color of \( I_2 \) is violet because it absorbs yellow and green light.
