Nothing happens to it. The speed of light is constant as long as it stays in the oil,
and although it changes as it crosses the boundary from one to the other, it stays
constant again once it's in the glass.

The speed decreases.
As long as the light remains in the motor oil, nothing happens to its speed.
It will not change. Glass slows light but does not change it frequency.
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.
When a ray of light hits glass, it can be reflected, refracted, or absorbed. Reflection happens when the light bounces off the surface of the glass, while refraction occurs when the light enters the glass and changes direction due to the change in speed between air and glass. Some of the light energy may also be absorbed by the glass material.
As the electromagnetic wave passes from air into glass, the frequency remains the same, but the speed decreases. This is due to the change in the medium's refractive index, which causes the wave to slow down as it travels through the denser medium of glass.
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
The speed of light depends on the electrical characteristics of whatever medium it happens to be in at that instant. It has one speed in vacuum, another speed in air, another in glass, another in water, and yet another speed in jello. When passing from a more-optically-dense medium to one where its speed is higher, it doesn't need a stomp on the gas to 'accelerate' to the higher speed.
When light passes from air to glass, it undergoes refraction, which is the bending of the light ray due to the change in speed as it moves from one medium to another. The speed of light is slower in glass compared to air, causing the light ray to bend towards the normal.
When light enters a glass block, it changes speed and bends due to refraction, causing the light beam to deviate from its original path. The light exits the glass block at a different angle than it entered. This phenomenon is a result of the change in the speed of light as it passes from air into the denser medium of the glass.
Light changes speed and direction when it goes from air into glass. This phenomenon is known as refraction. The change in speed causes the light to bend, which is why objects may appear distorted when viewed through a glass surface.
