Red light cannot be dispersed by a glass prism because it :

Options

A. has a high frequency
B. has a long wavelength
C. does not have component colors
D. is not refracted in glass

Explanation

**Step-by-Step Solution:**

1. **Understanding Dispersion of Light:**
- Dispersion of light occurs when white light passes through a prism and is separated into its component colors (spectrum) due to different wavelengths of light being refracted by different amounts.

2. **Characteristics of Red Light:**
- Red light is one of the colors in the visible spectrum and has a long wavelength compared to other colors like blue or violet.

3. **Why Red Light Cannot Be Dispersed:**
- Red light does not have component colors that can be separated. Unlike white light, which contains all colors, red light is a single color and does not break down into other colors when passing through a prism.

4. **Conclusion:**
- Therefore, red light cannot be dispersed by a glass prism because it does not have component colors that can be refracted and separated.

**Final Answer:**
Red light cannot be dispersed by a glass prism because it does not have component colors.
