The colour of white light which is deviated the maximum on passing through the glass prism is :

Options

A. blue
B. indigo
C. red
D. orange

Explanation

To solve the question regarding which color of white light is deviated the maximum when passing through a glass prism, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding White Light**: White light is made up of a spectrum of colors. When white light passes through a prism, it splits into these colors due to refraction.

2. **Identifying the Spectrum**: The colors of the spectrum are typically listed as red, orange, yellow, green, blue, indigo, and violet (ROYGBIV).

3. **Refraction and Deviation**: When light passes through a prism, different colors are refracted by different amounts. The amount of deviation depends on the wavelength of the light. Shorter wavelengths (like violet) are deviated more than longer wavelengths (like red).

4. **Determining Maximum Deviation**: Among the colors of the spectrum, violet has the shortest wavelength and is deviated the most. Conversely, red has the longest wavelength and is deviated the least.

5. **Analyzing the Options**: The question asks for the color that is deviated the maximum. If violet is not an option, we look at the next color in terms of wavelength, which is indigo.

6. **Conclusion**: Therefore, the color of white light that is deviated the maximum on passing through a glass prism is **indigo**.

### Final Answer:
The color of white light which is deviated the maximum on passing through the glass prism is **indigo**.
