What happens when light moves in which its speed is faster to a material in which its speed is slower?

The wavlength will become shorter.
Suppose two materials each have a "propagation velocity" (i.e. how fast light will travel inside the material. the first material is v1, the second is v2. The wavelength (l) of the lightwave will change according to:
l2/l1 = v2/v1
If the light is propagating at an angle relative to the boundary, then you will have a situation described by "Snells Law", which you can Google.

What happens when light passes into a material where the speed of light is lower?
It moves at a slower speed!
Is light faster than sound or sound is faster than light?
Light is faster than sound
Why does light travel faster in empty spaces?
Light travels faster (up to the speed of light) in a vacuum, which is empty space. Light travels slower through a medium (matter).
What happens when light passes into a material where the speed of light is faster?
-- Its speed increases. -- Its wavelength increases. -- It refracts away from the normal to the interface at the point of incidence.
Is there a tiny particle that can faster than the speed of light and sound?
no, not that i know of though but im sure nothing is faster than the speed of light and the speed of sound is slower than the light
What happens when light passes into a material where the speed of light is lower?
It moves at a slower speed!
Light travels slower in a material with greater what?
Light travels slower in a material with greater optical density.
Is light faster than sound or sound is faster than light?
Light is faster than sound
Why does light travel faster in empty spaces?
Light travels faster (up to the speed of light) in a vacuum, which is empty space. Light travels slower through a medium (matter).
Does light travel more faster or slower as they enter water?
Slower in water.
Does light travel faster in glass then it does in a vacuum?
No, slower.
Do windmills spin faster in light winds?
Slower..
Does light get faster when it moves?
In a vacuum, light travels at a constat speed. It won't get faster or slower over time. In other substances (e.g., in water) light moves at a speed determined by the characteristics of the substance. Here, it won't get slower or faster with time, either.
What happens when light passes into a material where the speed of light is faster?
-- Its speed increases. -- Its wavelength increases. -- It refracts away from the normal to the interface at the point of incidence.
How can you race the speed of light?
What do you mean, make it faster? In a vacuum, light travels at only one speed. There is no way to make it faster or slower. In other materials, light is usually slower. There are instances where it is actually measured to be faster, but it is generally believed that this can't be used to transfer matter, energy, or information, faster than the speed of light.
Is mach 20 faster than light If not how much slower?
No, Mach 20 is not faster than the speed of light. The speed of light is approximately 299,792,458 meters per second in a vacuum, while Mach 20 is roughly 7.35 kilometers per second. Therefore, Mach 20 is significantly slower than the speed of light.
Is the speed of sound faster or slower than light?
Way slower. For reference, the speed of sound is about 767.3 mph and the speed of light is 671,000,000 mph.
