Critical angle of the spectrum will be minimum at violent color.
The refractive angle of glass = μ - c/v
c= velocity of light
v= velocity of the color
In refraction violent color has the least refraction
μ= 1/ sinC
and C is the critical angle
by substituting the first equation in this we have
c/v = 1/ sin C
hence v is directly proportional to sin C
thus Critical angle is minimum for light with minimum v and that is violent
