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. property of `l_(2)`

Answer

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

### Step-by-Step Solution:

1. **Understanding Color Perception**:
- The color we perceive is the result of the wavelengths of light that are not absorbed by an object. Instead, we see the complementary color of the light that is absorbed.

2. **Identifying the Colors of White Light**:
- White light is made up of seven colors: Red, Orange, Yellow, Green, Blue, Indigo, and Violet (often remembered by the acronym ROYGBIV).

3. **Complementary Colors**:
- Each color has a complementary color that is perceived when the former is absorbed. For example:
- Violet is complementary to Yellow.
- Blue is complementary to Orange.
- Green is complementary to Red.

4. **Absorption of Light by \( I_2 \)**:
- Since \( I_2 \) appears violet, it indicates that it absorbs the colors that are complementary to violet. The complementary colors to violet are yellow and green.

5. **Conclusion**:
- Therefore, the color of \( I_2 \) is violet because it absorbs yellow and green light.

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