In water
Light travels faster in air compared to glass because the speed of light is inversely proportional to the refractive index of the medium. Air has a lower refractive index than glass, so light can move faster through air than through glass.
Blue light travels faster in crown glass compared to red light.
Light travels fastest through air, then glass, and slowest through water. The speed at which light travels through a medium depends on the refractive index of the material, with lower refractive indexes resulting in faster speeds.

Light travels faster through a vacuum than through any other medium, such as air, water, or glass. In a vacuum, light can travel at its maximum speed of approximately 299,792 kilometers per second.
True, the speed of light is faster in a transparent medium like water or glass compared to its speed in a vacuum. This difference in speed is due to the different refractive indexes of the medium, which affects the speed at which light travels through it.
The speed of light in any medium is given by its speed of light in vacuum divided by the refractive index of the medium and so light will travel faster in water than in glass since refractive index of glass is greater than that of water.
"air", "water" "glass" - generically a medium.
Blue light travels faster than red light through glass because blue light has a shorter wavelength and higher frequency, allowing it to pass through the glass with less scattering or absorption.
It is not. The speed of light in any material is inversely proportional to the refractive index of that material. The refractive index of glass depends on the glass and so the speed of light varies between 156 and 204 million metres per second. By contrast, the speed of light in vacuum is nearly 300 million metres per second.Even in pure water ice, light travels at nearly 229 million metres per second. So there is no evidence whatsoever to support the question's claim of "fastest through glass".
The color of light that travels through glass with the minimum speed is violet. This is because the speed of light in any medium, including glass, is dependent on the medium's refractive index, with shorter wavelengths like violet experiencing a slower speed.
