When light travels from air to glass it is called refraction. As it travels, the light ray slows down and bends towards the normal.
The normal is a line drawn at right angles to the boundary of the medium.
When light travels from air to glass, it slows down due to the increase in optical density, causing the light waves to bend towards the normal. This phenomenon is known as refraction. The speed of light in glass is slower than in air due to the higher refractive index of glass.
When light travels from air to glass, it slows down due to the higher refractive index of glass compared to air. This change in speed causes the light to bend towards the normal (an imaginary line perpendicular to the surface) at the point of entry. This bending of light is known as refraction.
When light travels from air into glass, it may not bend if it hits the glass surface perpendicular to it, which is called normal incidence. In this case, the speed of light doesn't change as it enters the glass, so there is no bending of the light ray. However, if the light hits the glass at an angle, it will bend due to the change in speed between air and glass, a phenomenon known as refraction.
"air", "water" "glass" - generically a medium.
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.
. . . decreases.
The ratio between the speed of light in vacuum, c, and the speed at which light travels in a material, v, is called the refractive index of the material.The refractive index of air for visible light is 1.000293, so the speed of light in air is c / 1.000293 ≈ 299,705,000 m/s. The refractive index of glass, depending on the type of glass, for visible light is around 1.5, so the light in glass travels at c / 1.5 ≈ 200,000,000 m/s.
The speed of light decreases when it travels from air into glass because the glass has a higher refractive index than air. This causes the light to slow down as it moves through the denser medium.

The speed of light is minimum in Glass. It is because light travels at minimum speed in solids.

The light refracts due to the change in speed. The change in speed occurs because the light is travelling through a denser medium. So it will travel fastest through the air and slowest through the glass
