Disperion of light is caused due to

Options

A. intensity of light
B. density of medium
C. wavelength
D. None of these

Explanation

### Step-by-Step Solution:

1. **Understanding Dispersion of Light**:
Dispersion of light refers to the phenomenon where white light splits into its constituent colors when it passes through a medium, such as a prism. This results in the appearance of a spectrum of colors.

2. **Identifying the Cause of Dispersion**:
When white light enters a prism, it is refracted at different angles. This refraction occurs because different colors (wavelengths) of light travel at different speeds in a medium.

3. **Role of Wavelength**:
The separation of colors happens due to the difference in wavelengths of the various colors present in white light. Each color has a different wavelength, and thus, they are refracted by different amounts when passing through the prism.

4. **Eliminating Other Options**:
- **Intensity of Light**: This does not affect the dispersion; it only affects the brightness of the light.
- **Density of Medium**: While the medium's density can affect the speed of light, it is not the primary cause of dispersion.
- **None of These**: This option is incorrect since dispersion is indeed caused by the difference in wavelengths.

5. **Conclusion**:
The correct answer to the question "Dispersion of light is caused due to" is the difference in wavelength of the colors present in the light.

### Final Answer:
Dispersion of light is caused due to the **wavelength** of the colors.
