The answer for this question is Violet colour which has minimum velocity and minimum critical angle.
Explanation:
We know that n= C/V
Where C is the speed of light in vacuum and
V IS THE velocity of light in given media.
We also know that n= 1/ sinc
So C/ V= 1/ Sinc
C is directly proportional to Critical angle.
Hence minimum velocity, minimum will be critical angle.
So violet colour is answer.

The answer of your question is "Violet color"
This is because the violet color has minimum velocity.
as we know that the refractive index is equal to the c/v
Here ''c'' is actually representing the light speed in vacuum while ''v'' represents light velocity in the given medium
So, refractive index=μ= c/v
we also know that μ is actually equals to 1/sin C
Here, sin C represents the critical angle.
So we can also write 1/sin C = c/v
Thus, we can also say that velocity is directly propertional to Sin C which is actually the critical angle so having the minimum velocity means having the minimum critical angle.
