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.

REd
Critical angle of a medium depends on refractive index of the medium. Different colors of light have different wavelengths have different refractive indices.

Red color will travel fastest in air and Blue color will travel slowest

Red light does.
fu** ur self..... what is the angle of min devi for a violet color
When light in glass of index of refraction n hits the surface at angle A relative to the surface normal (perpendicular line to the surface) it generally exits into the air at larger angle B. These three variables are related by Snell's Law: n Sin(A) = (1)Sin(B) (air has index of refraction approx. = 1 ) The critical angle A for internal reflection occurs when the exit angle is 90 so the exit light skims the surface. Anything larger then critical A and the light gets reflected back into the glass. So in Snell's law let B = 90; nSin(A) =(1)Sin(90) = (1)(1) so Sin(A) = 1/n For glass n ~ 1.5 so Sin(A) ~ .67 This is the sine of the critical angle. Now figure out what angle has a sign of .67 and Whala you have it.
The "No Passing Zone" sign is a triangular "pennant" shape, pointing to the right side. It is either yellow or orange in color.

The angle you are looking at, and the lighting.
The role that the passing down of traits through DNA have on families, and the characteristics they share is physical appearance such as; height, skin color, hair color, and eye color.
Red color will travel fastest in air and Blue color will travel slowest
