the speed never changes
When a light ray passes from one medium to another at an angle, it undergoes refraction, changing direction due to the difference in the speed of light in the two mediums. The angle of refraction is determined by Snell's Law, which relates the angles of incidence and refraction to the refractive indices of the two mediums.
When light passes from one medium to another, its speed changes, causing it to bend. This phenomenon is known as refraction. The amount of bending depends on the change in the speed of light and the angle at which it enters the new medium.
The angle of incidence is always greater than the angle of refraction. The refractive index of glass is greater than that of air, so the speed of light in air is more than the speed of light in glass. Therefore it slows down and bends towards the normal.
When light passes perpendicularly from a rarer medium to a denser medium, there is no change in the speed of light. Since refraction occurs due to the change in speed, the absence of speed change in this case results in no bending of the light ray.
When light waves travel from air to glass, the variables that are affected include the speed of light (slows down in glass compared to air), the angle of refraction (changes as light enters the glass at an angle), and the wavelength of the light (may change due to the different medium).

When light traveling at an angle passes from one material into another, it undergoes refraction. Refraction is the bending of light as it passes from one medium to another, due to the change in the speed of light. The degree to which the light bends depends on the angle of incidence and the refractive indices of the materials involved.

When light passes from air to water, the light is refracted because water is denser than air and therefore slows down the speed of the light.
The light will bend away from the normal as it enters the material where its speed is higher. This bending of light is known as refraction. The amount of bending depends on the difference in the speed of light between the two materials.
Every substance has its own index of refraction. The index of refraction affects the speed of the light passing through it. Air has an index of refraction of about 1.00 whereas water has an index of refraction of about 1.33. a simple ratio formula can be used to determine the final speed of the light through the water. (Vi/Vf)=(Ni/Nf) where v is the speed of light and N is the index of refraction. The angle would also change. The path of the light would 'bend' toward the normal line which is an imaginary line that runs perpendicular to the line where the air meets the water. Equation to find angle is (N2/N1) = Sin(angle1)/Sin(angle2).
Light bends when it passes from one medium into another with a different refractive index, causing a change in its speed. The angle at which light bends is determined by Snell's Law, which relates the angles of incidence and refraction to the refractive indices of the two media.
Light bends towards the denser medium. If the light passes at an angle from air into water the angle will increase. An object underwater will appear closer to you than it actually is when you look down into the water at an angle.
It moves at a slower speed!
