Name the constituent colour of white light for which
the deviation produced by the glass prism is least

Explanation

To solve the question, we need to identify the constituent color of white light that experiences the least deviation when passing through a glass prism.

### Step-by-step Solution:

1. **Understanding White Light**: White light is composed of several colors, which can be separated into a spectrum. The colors of the spectrum, in order of increasing wavelength, are violet, indigo, blue, green, yellow, orange, and red.

2. **Concept of Deviation in a Prism**: When white light passes through a prism, each color is refracted at a different angle due to their different wavelengths. The degree of deviation depends on the refractive index of the material for each color.
