No, it is only refracted at each clear air to glass surface, even if the refractive index of the glass changes.
If an air to glass lens is vacuum coated with a fluoride film, it impoves the tranmision of light through the lens, e.g. the front lens of a telescope. The film can improve the tranmission of light by one half of a wave length. This trechnolgy was used by the British Navy during WW2 against the German warship the Graff Spay and others. The British vessels were able to see the enemy before they could be seen and were able to fire the first shots.

The colour of light which travels through glass with the minimum speed is?
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.
What happens to the speed of light when it travels from air into glass?
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.
How does the speed of light compare in water glass and diamond?

Slow glass that reduces the speed of light?
Most forms of glass do not change the speed of light. Darker glass lets less light through it Glass at an angle to light may refract ( bend) light or glass may break light up into all the colours the light is made of rainbow / spectrum. The only way anyone has successfully stopped and restarted light is using magnetic beams
What happens to the speed of light when it passes from water to glass?
the speed of light it different when it is passed through air, water or glass because all these have different optical densities. Speed of light is fastest in air, slower in water and slowest in glass.
The colour of light which travels through glass with the minimum speed is?
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.
How does light passing through glass affect its speed and direction?
When light passes through glass, its speed decreases and it bends, or refracts, due to the change in the medium.
What happens to the speed of the light as it travels from the air through the glass and then through the water?
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
How does the speed of light in glass compare to the speed of light in a vacuum?
It will depend on the type of glass, and something called its refractive index. All materials have a refractive index which will effect the speed of the light through it. The speed of light through a vacuum is 3.0x10^8 m/s, and a material such as glass will be lower than this.
How does light behaves when it travels from air through glass?
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.
What happens when light passes through a glass block?
When light passes through a glass block, it undergoes refraction, which is the bending of light as it enters the glass and again as it exits. The speed of light changes as it moves from air to glass, causing the light rays to change direction.
Does speed of light increases when it comes in contact with black hole gravity?
No, it does not. The speed of light always remains constant; it may be slowed down slightly when travelling through certain mediums (e.g. water, glass, air), but it cannot increase.
When light goes through a glass window the light is primarily what?
When light goes through a glass window, the light is primarily transmitted and refracted. Transmitted light passes through the glass without being absorbed or reflected, while refraction is the bending of light as it enters and exits the glass due to the change in speed.
Where will be speed of light minimum-water or air or vacuum or glass?
The speed of light is minimum in Glass. It is because light travels at minimum speed in solids.
What happened when a ray of light is shone at a glass block?
It all depends on the angle if incidence. In general the light will refract i.e. bend through the glass and come out at the other end. Also, the speed of light will vary through the glass.
What can happen to light traveling through a glass filled with water?
Light traveling through a glass filled with water will experience refraction, causing it to change speed and direction. The change in speed is due to the difference in optical density between the glass, water, and air. The bending of light at the interface of water and glass is what causes the phenomenon of refraction.
What happens to the speed of light when it travels from air into glass?
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.
