red
The color of light that has the minimum critical angle when passing from glass to air is red. This is because red light has the longest wavelength of all the visible colors, which leads to a smaller change in speed and a larger angle of refraction at the interface between the two mediums.
Violet. In dispersion of white light, red comes first as it has the smallest angle of refraction, then Orange, Yellow, Green, Blue, Indigo and finally Violet, with the largest angle of refraction.
Diffraction angle is roughly proportional to wavelength (see ref.), so for a given order minimum, red diffracts more than violet light. But red is the longer wavelength, not the shorter. LONGER
Violet light has a higher index of refraction than red or blue because it is a higher frequency wave. Violet light will have the largest angle of deviation during the process of dispersion.

fu** ur self..... what is the angle of min devi for a violet color

Violet and red-violet are made of red and blue.
