Light travels through different things (such as air, water, glass, plastic) at different speeds. When a light wave is passing one substance and encounters another (for instance, traveling through air and gets to glass), the difference in the speed causes the light wave to bend. This is what causes rainbows and a spectrum and fish to appear in a different place than where they really are.

What happens to speed of light when travel through plastic?
When light travels through anything that is not a vacuum, it will usually slow down.
What happens when electrons travel through a filament?
When electrons travel through a filament, they collide with atoms in the filament material. These collisions cause the electrons to lose energy and heat up the filament, which then emits light. This process is how an incandescent light bulb produces light.
Can light travel through matter?
Yes! Light travels through any material that does not completely absorb it. Visible light can only travel through materials that are called either transparent or translucent. Visible light travels through glass all the time. Visible light also travels through your cornea and the gel-like material that is in your eyeball. There are other types of light than visible light, such as ultraviolet (UV). UV is light that has more energy than visible light. This is the type of light that can give you a sunburn. There are even more energetic types of light like X-rays. They go through lots of material that visible light can't -- like skin and organs, but they do not go through bones or teeth very well.
What happens to light waves when two materials do not have similar indexes of refraction?
Nothing happens to light waves at all. UNLESS the two materials happen to be right next to each other AND the light tries to cross FROM one INTO the other one. Then things get very interesting.
Why there is no sound year like light year?
The velocity of light in vacuum is a universal constant. A light year is the distance travelled at that velocity in one year. To define a sound year it would be necessary to also specify the precise characteristics of material it is being propagated through. A vacuum won't do, since sound doesn't travel through a vacuum.
What happens when light passes through a prism and is refracted?
When light passes through a prism, it is refracted, which means it is bent or separated into different colors. This happens because light waves travel at different speeds through different materials, causing them to change direction.
What do you call things that let light travel through them?
Materials that allow light to pass through them are called transparent materials.
What is a material that light can't travel through?
There is no known material that light cannot travel through. However, materials such as lead and thick concrete can significantly attenuate or absorb light, making them almost opaque to visible light.
What does not let light through?
There are many materials that light can not travel through which are called opaque objects.
What can light travel through that sound cant travel through?
Light can travel through a vacuum, such as outer space, where sound cannot travel as it requires a medium like air, water, or a solid to propagate. Light can also travel through transparent materials like glass or air, while sound is mostly blocked or absorbed by these materials.
Materials through which light can travel in straight lines are?
Transparent
Does light travel at different speeds through different materials?
no
What are 3 materials mediums light can travel through?
Air, water, and glass are three common materials that light can travel through. Each material has different properties that affect how light travels through it, such as its density and refractive index.
Through what can light waves travel?
Light waves can travel through a vacuum, air, water, and transparent materials like glass and plastic.
A material that light can travel through is?
A material that light can travel through is called a transparent material. These materials allow light to pass through without scattering or being absorbed. Glass, air, and water are examples of transparent materials.
In what does light travel?
Light travels in a straight line through a vacuum or transparent materials.
How does light travel through materials that are not transparent, such as wood or aluminum foil?
When light encounters materials that are not transparent, like wood or aluminum foil, it is either absorbed or reflected. Absorption occurs when the material takes in the light energy, while reflection happens when the light bounces off the surface of the material. This is why these materials appear opaque, as they do not allow light to pass through them.
