In visible region the dispersive powers and the mean angular deviation...
The dispersive power is a measure of the degree to which a medium (such as a prism) separates different colors of light. It is defined as the difference in index of refraction between the red and violet ends of the spectrum.

For crown glass, the dispersive power is about 0.0146, while for flint glass it is about 0.0228. This means that flint glass has a higher dispersive power, and will separate colors more effectively.

The mean angular deviation is a measure of the amount that light is bent as it passes through a prism. It is defined as the average angle between the incident and emergent rays of light.

For crown glass, the mean angular deviation is about 0.56 degrees, while for flint glass it is about 0.82 degrees. This means that flint glass bends light more than crown glass, resulting in a greater separation of colors.

Overall, these differences in dispersive power and mean angular deviation make flint glass more effective at dispersing light and creating a rainbow effect, while crown glass is better suited for applications where a high degree of precision is required.
